We divide 63839485 by 780
We want to figure out the number of times 63839485 can be divided by 780.

Moving on to step 1:
If we divide 6 by 780, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 780

Advancing to step 2:
When dividing 63 by 780, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 63 after subtracting 0 from 63.
Include the next digit (8) from the dividend after 63, then repeat: 638 / 780

On to step 3:
638 divided by 780 is 0 with a remainder of 638.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 638 and we're left with 638.
Bring next digit (3) of the dividend behind the 638 and repeat the process: 6383 / 780

Going ahead to step 4:
When dividing 6383 by 780, we get 8 with a remainder of 143.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 6240 from 6383 and we're left with 143.
Include the next digit (9) from the dividend after 143, then repeat: 1439 / 780

Advancing to step 5:
The number 780 fits into 1439 1 times, leaving a remainder of 659.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 780 from 1439, we get 659.
Grab the next digit (4) from the dividend, add it to 659, then carry on: 6594 / 780

Moving on to step 6:
780 goes into 6594 8 times with a remainder of 354.
The next digit of our result is 8. 
Result so far: 818.0
Subtracting 6240 from 6594 leaves us with 354.
Append the next digit (8) from the dividend to 354 and continue with: 3548 / 780

Going ahead to step 7:
780 can be fit into 3548 4 times, resulting in a remainder of 428.
Use 4 as the next digit of our solution. 
Result so far: 8184.0
The remainder is 428 after subtracting 3120 from 3548.
Bring next digit (5) of the dividend behind the 428 and repeat the process: 4285 / 780

On to step 8:
780 can be fit into 4285 5 times, resulting in a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 81845.0
Subtracting 3900 from 4285 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Advancing to step 9:
The number 780 fits into 3850 4 times, leaving a remainder of 730.
Record the quotient 4 as the next digit in the result. 
Result so far: 81845.4
If we subtract 3120 from 3850, we get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Step 10:
7300 divided by 780 is 9 with a remainder of 280.
The next digit of our result is 9. 
Result so far: 81845.49
Subtracting 7020 from 7300 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
The number 780 fits into 2800 3 times, leaving a remainder of 460.
Record the quotient 3 as the next digit in the result. 
Result so far: 81845.493
If we subtract 2340 from 2800, we get 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Step 12:
780 goes into 4600 5 times with a remainder of 700.
The number 5 becomes the next digit in our result. 
Result so far: 81845.4935
Subtract 3900 from 4600 to get 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Going ahead to step 13:
7000 divided by 780 is 8 with a remainder of 760.
Write down 8 as next digit of the result. 
Result so far: 81845.49358
Subtracting 6240 from 7000 leaves us with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Let's proceed to step 14:
780 can be fit into 7600 9 times, resulting in a remainder of 580.
The number 9 becomes the next digit in our result. 
Result so far: 81845.493589
Subtracting 7020 from 7600 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 15:
780 goes into 5800 7 times with a remainder of 340.
Record the quotient 7 as the next digit in the result. 
Result so far: 81845.4935897
Subtracting 5460 from 5800 leaves us with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 16:
If we divide 3400 by 780, we get 4 and a remainder of 280.
The number 4 becomes the next digit in our result. 
Result so far: 81845.49358974
Deduct 3120 from 3400 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Our division results in 81845.49358974 with a remaining 2.8e-07.
