478635 divided by 15 
Let's see how many times 15 fits into 478635.

Going ahead to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 15

Moving on to step 2:
47 divided by 15 is 3 with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 45 from 47, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 15

Let's proceed to step 3:
If we divide 28 by 15, we get 1 and a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 31.0
The remainder is 13 after subtracting 15 from 28.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 15

Going ahead to step 4:
When dividing 136 by 15, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 319.0
The remainder is 1 after subtracting 135 from 136.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 15

Advancing to step 5:
15 goes into 13 0 times with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 3190.0
If we take 0 away from 13, we end up with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 15

Let's proceed to step 6:
15 goes into 135 9 times with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 31909.0
The remainder is 0 after subtracting 135 from 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 15, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31909.0
The remainder is 0 after subtracting 0 from 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 8:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31909.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 31909.0 with a remainder of 0.0.
