We divide 129535 by 15
We want to figure out the number of times 129535 can be divided by 15.

Let's proceed to step 1:
When dividing 1 by 15, we get 0 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 / 15

Let's proceed to step 2:
12 divided by 15 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 15

On to step 3:
The number 15 fits into 129 8 times, leaving a remainder of 9.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 120 from 129, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 15

Advancing to step 4:
When dividing 95 by 15, we get 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 86.0
If we subtract 90 from 95, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 15

Let's proceed to step 5:
The number 15 fits into 53 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 863.0
Subtracting 45 from 53 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 15

Going ahead to step 6:
The number 15 fits into 85 5 times, leaving a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 8635.0
Subtracting 75 from 85 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 8635.6
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 8635.66
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 8635.66 with a remainder of 0.01.
