We divide 780435 by 77
Let's see how many times 77 fits into 780435.

On to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 77

Step 2:
77 can be fit into 78 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 77 away from 78, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 77

Advancing to step 3:
10 divided by 77 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 77

Step 4:
If we divide 104 by 77, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 101.0
Deduct 77 from 104 and we're left with 27.
Take the next digit (3) from the dividend and append it to 27, then repeat: 273 / 77

Moving on to step 5:
77 can be fit into 273 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 1013.0
If we subtract 231 from 273, we get 42.
Include the next digit (5) from the dividend after 42, then repeat: 425 / 77

Moving on to step 6:
If we divide 425 by 77, we get 5 and a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 10135.0
If we take 385 away from 425, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
77 can be fit into 400 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10135.5
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
77 goes into 150 1 times with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 10135.51
If we subtract 77 from 150, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 9:
77 goes into 730 9 times with a remainder of 37.
The next digit of our result is 9. 
Result so far: 10135.519
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 10:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 10135.5194
Subtracting 308 from 370 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 11:
620 divided by 77 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10135.51948
If we subtract 616 from 620, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
77 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 10135.51948
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 13:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 10135.5194805
Subtract 385 from 400 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 14:
150 divided by 77 is 1 with a remainder of 73.
Write down 1 as next digit of the result. 
Result so far: 10135.51948051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 10135.51948051, and the remainder is 7.3e-08.
