We look at the division of 285859 by 15 
Let's see how many times 15 fits into 285859.

Moving on to step 1:
The number 15 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 15

On to step 2:
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: 1.0
The remainder is 13 after subtracting 15 from 28.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 15

Going ahead to step 3:
When dividing 135 by 15, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 135 from 135 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 15

Let's proceed to step 4:
15 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

Going ahead to step 5:
If we divide 85 by 15, we get 5 and a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 1905.0
The remainder is 10 after subtracting 75 from 85.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 15

Let's proceed to step 6:
If we divide 109 by 15, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 19057.0
Deduct 105 from 109 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 15 is 2 with a remainder of 10.
Record the quotient 2 as the next digit in the result. 
Result so far: 19057.2
The remainder is 10 after subtracting 30 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 19057.26
If we take 90 away from 100, 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.

Let's proceed 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: 19057.266
If we take 90 away from 100, 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.

In conclusion, the division gives 19057.266 with a balance of 0.001.
