We're dividing 431535 by 15 
We want to figure out the number of times 431535 can be divided by 15.

Moving on to step 1:
15 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 15

Moving on to step 2:
The number 15 fits into 43 2 times, leaving a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 30 from 43, we get 13.
Take the next digit (1) from the dividend and append it to 13, then repeat: 131 / 15

Let's proceed to step 3:
15 can be fit into 131 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtracting 120 from 131 leaves us with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 15

Let's proceed to step 4:
115 divided by 15 is 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 287.0
If we take 105 away from 115, we end up with 10.
Take the next digit (3) from the dividend and append it to 10, then repeat: 103 / 15

Advancing to step 5:
15 goes into 103 6 times with a remainder of 13.
The next digit of our result is 6. 
Result so far: 2876.0
Subtracting 90 from 103 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Moving on to step 6:
135 divided by 15 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 28769.0
Subtracting 135 from 135 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.

Advancing to step 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28769.0
If we subtract 0 from 0, we 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.

Advancing to step 8:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28769.0
If we subtract 0 from 0, we 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 outcome is 28769.0, with a leftover of 0.0.
