We look at the division of 129575 by 15 
We want to divide 129575 by 15.

Going ahead to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

Let's proceed to step 2:
The number 15 fits into 12 0 times, leaving a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 15

Moving on to step 3:
129 divided by 15 is 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 120 away from 129, we end up with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 15

Moving on to step 4:
If we divide 95 by 15, we get 6 and a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
If we take 90 away from 95, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 15

Let's proceed to step 5:
57 divided by 15 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 863.0
Subtracting 45 from 57 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 15

Advancing to step 6:
When dividing 125 by 15, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 8638.0
Subtract 120 from 125 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
If we divide 50 by 15, we get 3 and a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 8638.3
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 8638.33
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 8638.33 with a remainder of 0.005.
