129644 ÷ 99 
We want to divide 129644 by 99.

On to step 1:
99 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 99

Step 2:
99 goes into 12 0 times with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 99

Going ahead to step 3:
The number 99 fits into 129 1 times, leaving 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.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 99

Moving on to step 4:
99 goes into 306 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 297 from 306 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 99

Moving on to step 5:
94 divided by 99 is 0 with a remainder of 94.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
Subtracting 0 from 94 leaves us with 94.
Bring next digit (4) of the dividend behind the 94 and repeat the process: 944 / 99

Going ahead to step 6:
99 goes into 944 9 times with a remainder of 53.
Put 9 as the next digit of the answer. 
Result so far: 1309.0
The remainder is 53 after subtracting 891 from 944.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
99 goes into 530 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 1309.5
The remainder is 35 after subtracting 495 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
99 goes into 350 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 1309.53
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
530 divided by 99 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 1309.535
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 10:
350 divided by 99 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 1309.5353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 11:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 1309.53535
Subtracting 495 from 530 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 12:
The number 99 fits into 350 3 times, leaving a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 1309.535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 13:
99 can be fit into 530 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1309.5353535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 99, we get 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 1309.53535353
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

After the division, we end up with 1309.53535353 and a remainder of 5.3e-08.
