We look at the division of 285435 by 15 
Our goal is to divide 285435 by 15.

Step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 15

Step 2:
15 can be fit into 28 1 times, resulting in a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 15 from 28, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Step 3:
When dividing 135 by 15, we get 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
Subtracting 135 from 135 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 15

Moving on to step 4:
The number 15 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 15

Step 5:
If we divide 43 by 15, we get 2 and a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 1902.0
Deduct 30 from 43 and we're left with 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 15

Step 6:
135 divided by 15 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19029.0
If we subtract 135 from 135, 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.

Going ahead to step 7:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19029.0
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.

On to step 8:
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: 19029.0
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 result is 19029.0 with a remainder of 0.0.
