129793 divided by 99 
We're looking to find how many times 99 goes into 129793.

Moving on to step 1:
99 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 99

Moving on to step 2:
99 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 99

Moving on to step 3:
99 goes into 129 1 times with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 99 from 129 leaves us with 30.
Bring next digit (7) of the dividend behind the 30 and repeat the process: 307 / 99

Step 4:
If we divide 307 by 99, we get 3 and a remainder of 10.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 297 from 307, we get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 99

Moving on to step 5:
The number 99 fits into 109 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 131.0
Subtract 99 from 109 to get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 99

Advancing to step 6:
When dividing 103 by 99, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1311.0
If we take 99 away from 103, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
The number 99 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 1311.0
If we take 0 away from 40, 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.

Moving on to step 8:
The number 99 fits into 400 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1311.04
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
If we divide 40 by 99, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1311.04
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
When dividing 400 by 99, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 1311.0404
If we subtract 396 from 400, 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.

Step 11:
99 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1311.0404
If we take 0 away from 40, 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.

Step 12:
The number 99 fits into 400 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 1311.040404
Subtract 396 from 400 to 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.

Step 13:
If we divide 40 by 99, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 1311.040404
If we subtract 0 from 40, we get 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 14:
99 goes into 400 4 times with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 1311.04040404
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 1311.04040404 with a remaining 4e-09.
