Let's divide 99537596 by 129
Let's see how many times 129 fits into 99537596.

Advancing to step 1:
The number 129 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 129

Advancing to step 2:
The number 129 fits into 99 0 times, leaving a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 129

Going ahead to step 3:
995 divided by 129 is 7 with a remainder of 92.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 903 from 995 and we're left with 92.
Take the next digit (3) from the dividend and append it to 92, then repeat: 923 / 129

Let's proceed to step 4:
129 can be fit into 923 7 times, resulting in a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
The remainder is 20 after subtracting 903 from 923.
Bring next digit (7) of the dividend behind the 20 and repeat the process: 207 / 129

On to step 5:
207 divided by 129 is 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 771.0
Subtract 129 from 207 to get 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 129

On to step 6:
When dividing 785 by 129, we get 6 with a remainder of 11.
The next digit of our result is 6. 
Result so far: 7716.0
If we subtract 774 from 785, we get 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 129

On to step 7:
129 can be fit into 119 0 times, resulting in a remainder of 119.
Record the quotient 0 as the next digit in the result. 
Result so far: 77160.0
If we take 0 away from 119, we end up with 119.
Append the next digit (6) from the dividend to 119 and continue with: 1196 / 129

Going ahead to step 8:
When dividing 1196 by 129, we get 9 with a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 771609.0
Subtracting 1161 from 1196 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.

On to step 9:
If we divide 350 by 129, we get 2 and a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 771609.2
The remainder is 92 after subtracting 258 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 10:
The number 129 fits into 920 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 771609.27
If we subtract 903 from 920, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
The number 129 fits into 170 1 times, leaving a remainder of 41.
Use 1 as the next digit of our solution. 
Result so far: 771609.271
Subtracting 129 from 170 leaves us 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.

On to step 12:
129 goes into 410 3 times with a remainder of 23.
Write down 3 as next digit of the result. 
Result so far: 771609.2713
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 13:
If we divide 230 by 129, we get 1 and a remainder of 101.
The next digit of our result is 1. 
Result so far: 771609.27131
Deduct 129 from 230 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 14:
129 can be fit into 1010 7 times, resulting in a remainder of 107.
The next digit of our result is 7. 
Result so far: 771609.271317
The remainder is 107 after subtracting 903 from 1010.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Going ahead to step 15:
129 can be fit into 1070 8 times, resulting in a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 771609.2713178
If we subtract 1032 from 1070, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 16:
129 can be fit into 380 2 times, resulting in a remainder of 122.
Put 2 as the next digit of the answer. 
Result so far: 771609.27131782
If we take 258 away from 380, we end up with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

After the division, we end up with 771609.27131782 and a remainder of 1.22e-07.
