Let's divide 915791 by 99
We want to divide 915791 by 99.

Step 1:
9 divided by 99 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 99

Moving on to step 2:
When dividing 91 by 99, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 91 to get 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 99

On to step 3:
The number 99 fits into 915 9 times, leaving a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 891 from 915 and we're left with 24.
Append the next digit (7) from the dividend to 24 and continue with: 247 / 99

Let's proceed to step 4:
99 can be fit into 247 2 times, resulting in a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
The remainder is 49 after subtracting 198 from 247.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 99

On to step 5:
499 divided by 99 is 5 with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 925.0
Subtracting 495 from 499 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 99

Step 6:
The number 99 fits into 41 0 times, leaving a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 9250.0
Deduct 0 from 41 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 7:
410 divided by 99 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 9250.4
If we subtract 396 from 410, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
The number 99 fits into 140 1 times, leaving a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 9250.41
Deduct 99 from 140 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
The number 99 fits into 410 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 9250.414
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
99 can be fit into 140 1 times, resulting in a remainder of 41.
The next digit of our result is 1. 
Result so far: 9250.4141
The remainder is 41 after subtracting 99 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 11:
When dividing 410 by 99, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 9250.41414
If we take 396 away from 410, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 12:
When dividing 140 by 99, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 9250.414141
Deduct 99 from 140 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 13:
99 goes into 410 4 times with a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 9250.4141414
Deduct 396 from 410 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
99 goes into 140 1 times with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 9250.41414141
If we subtract 99 from 140, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 9250.41414141 with a remainder of 4.1e-08.
