Let's divide 256063 by 15
Let's see how many times 15 fits into 256063.

Advancing to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 15

Moving on to step 2:
25 divided by 15 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 15 from 25 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 15

Advancing to step 3:
15 can be fit into 106 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 105 away from 106, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 15

Let's proceed to step 4:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 170.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 15

On to step 5:
When dividing 106 by 15, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1707.0
The remainder is 1 after subtracting 105 from 106.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 15

On to step 6:
The number 15 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 17070.0
The remainder is 13 after subtracting 0 from 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
15 can be fit into 130 8 times, resulting in a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 17070.8
If we take 120 away from 130, we end up 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.

Going ahead to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 17070.86
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 9:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 17070.866
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.

The final result is 17070.866 with a remainder of 0.001.
