We divide 90744521 by 780
We want to figure out the number of times 90744521 can be divided by 780.

Advancing to step 1:
When dividing 9 by 780, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 780

Moving on to step 2:
780 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (7) from the dividend after 90, then repeat: 907 / 780

Advancing to step 3:
If we divide 907 by 780, we get 1 and a remainder of 127.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 780 from 907 to get 127.
Fetch the next digit (4) from the dividend, attach it to 127 and continue: 1274 / 780

Going ahead to step 4:
780 goes into 1274 1 times with a remainder of 494.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 780 from 1274, we get 494.
Take the next digit (4) from the dividend and append it to 494, then repeat: 4944 / 780

Let's proceed to step 5:
If we divide 4944 by 780, we get 6 and a remainder of 264.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
The remainder is 264 after subtracting 4680 from 4944.
Include the next digit (5) from the dividend after 264, then repeat: 2645 / 780

Advancing to step 6:
The number 780 fits into 2645 3 times, leaving a remainder of 305.
The number 3 becomes the next digit in our result. 
Result so far: 1163.0
Deduct 2340 from 2645 and we're left with 305.
Include the next digit (2) from the dividend after 305, then repeat: 3052 / 780

Advancing to step 7:
When dividing 3052 by 780, we get 3 with a remainder of 712.
The number 3 becomes the next digit in our result. 
Result so far: 11633.0
Subtract 2340 from 3052 to get 712.
Grab the next digit (1) from the dividend, add it to 712, then carry on: 7121 / 780

Step 8:
780 can be fit into 7121 9 times, resulting in a remainder of 101.
Put 9 as the next digit of the answer. 
Result so far: 116339.0
If we subtract 7020 from 7121, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
If we divide 1010 by 780, we get 1 and a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 116339.1
The remainder is 230 after subtracting 780 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Step 10:
2300 divided by 780 is 2 with a remainder of 740.
Record the quotient 2 as the next digit in the result. 
Result so far: 116339.12
Subtracting 1560 from 2300 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Let's proceed to step 11:
The number 780 fits into 7400 9 times, leaving a remainder of 380.
The number 9 becomes the next digit in our result. 
Result so far: 116339.129
The remainder is 380 after subtracting 7020 from 7400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 12:
When dividing 3800 by 780, we get 4 with a remainder of 680.
The next digit of our result is 4. 
Result so far: 116339.1294
The remainder is 680 after subtracting 3120 from 3800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

On to step 13:
When dividing 6800 by 780, we get 8 with a remainder of 560.
The number 8 becomes the next digit in our result. 
Result so far: 116339.12948
If we take 6240 away from 6800, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 14:
780 goes into 5600 7 times with a remainder of 140.
Put 7 as the next digit of the answer. 
Result so far: 116339.129487
Subtracting 5460 from 5600 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 15:
If we divide 1400 by 780, we get 1 and a remainder of 620.
Record the quotient 1 as the next digit in the result. 
Result so far: 116339.1294871
Deduct 780 from 1400 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 16:
When dividing 6200 by 780, we get 7 with a remainder of 740.
Record the quotient 7 as the next digit in the result. 
Result so far: 116339.12948717
Subtracting 5460 from 6200 leaves us with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

In conclusion, the division gives 116339.12948717 with a balance of 7.4e-07.
