129791 ÷ 99 
Let's see how many times 99 fits into 129791.

Going ahead to step 1:
99 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 99

On to step 2:
99 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 99

Going ahead to step 3:
99 can be fit into 129 1 times, resulting in a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 30 after subtracting 99 from 129.
Append the next digit (7) from the dividend to 30 and continue with: 307 / 99

Advancing to step 4:
99 goes into 307 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 297 from 307, we get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 99

Step 5:
99 goes into 109 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 131.0
If we take 99 away from 109, we end up with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 99

Going ahead to step 6:
When dividing 101 by 99, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1311.0
The remainder is 2 after subtracting 99 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 99, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1311.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
99 goes into 200 2 times with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 1311.02
Subtracting 198 from 200 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 99, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1311.02
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
99 can be fit into 200 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 1311.0202
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
The number 99 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1311.0202
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
The number 99 fits into 200 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 1311.020202
Deduct 198 from 200 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
If we divide 20 by 99, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1311.020202
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
200 divided by 99 is 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 1311.02020202
The remainder is 2 after subtracting 198 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 1311.02020202 and a remainder of 2e-09.
