We're dividing 129477 by 15 
We want to figure out the number of times 129477 can be divided by 15.

On to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 15

On to step 2:
15 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 15

Going ahead to step 3:
129 divided by 15 is 8 with a remainder of 9.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 120 from 129 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

Let's proceed to step 4:
The number 15 fits into 94 6 times, leaving a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
The remainder is 4 after subtracting 90 from 94.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 15

Moving on to step 5:
When dividing 47 by 15, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 863.0
The remainder is 2 after subtracting 45 from 47.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 15

Going ahead to step 6:
If we divide 27 by 15, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 8631.0
The remainder is 12 after subtracting 15 from 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 8631.8
If we take 120 away from 120, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8631.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8631.8
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 8631.8 with a remaining 0.0.
