We look at the division of 877731 by 99 
We're looking to find how many times 99 goes into 877731.

Going ahead to step 1:
8 divided by 99 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 99

On to step 2:
When dividing 87 by 99, we get 0 with a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 87, we get 87.
Fetch the next digit (7) from the dividend, attach it to 87 and continue: 877 / 99

Step 3:
877 divided by 99 is 8 with a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 792 from 877, we get 85.
Take the next digit (7) from the dividend and append it to 85, then repeat: 857 / 99

Moving on to step 4:
99 can be fit into 857 8 times, resulting in a remainder of 65.
Write down 8 as next digit of the result. 
Result so far: 88.0
The remainder is 65 after subtracting 792 from 857.
Grab the next digit (3) from the dividend, add it to 65, then carry on: 653 / 99

Step 5:
The number 99 fits into 653 6 times, leaving a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 886.0
If we take 594 away from 653, we end up with 59.
Append the next digit (1) from the dividend to 59 and continue with: 591 / 99

Step 6:
The number 99 fits into 591 5 times, leaving a remainder of 96.
The number 5 becomes the next digit in our result. 
Result so far: 8865.0
Subtract 495 from 591 to get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 7:
If we divide 960 by 99, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 8865.9
The remainder is 69 after subtracting 891 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 8:
99 goes into 690 6 times with a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 8865.96
If we subtract 594 from 690, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 9:
99 goes into 960 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 8865.969
Subtracting 891 from 960 leaves us with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Advancing to step 10:
The number 99 fits into 690 6 times, leaving a remainder of 96.
The next digit of our result is 6. 
Result so far: 8865.9696
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 11:
960 divided by 99 is 9 with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 8865.96969
If we subtract 891 from 960, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 12:
99 can be fit into 690 6 times, resulting in a remainder of 96.
The next digit of our result is 6. 
Result so far: 8865.969696
The remainder is 96 after subtracting 594 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 13:
If we divide 960 by 99, we get 9 and a remainder of 69.
The next digit of our result is 9. 
Result so far: 8865.9696969
Subtract 891 from 960 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 14:
When dividing 690 by 99, we get 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 8865.96969696
Deduct 594 from 690 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Our division results in 8865.96969696 with a remaining 9.6e-08.
