Let's divide 285107 by 15
We want to divide 285107 by 15.

Step 1:
2 divided by 15 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 15

On to step 2:
15 goes into 28 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 15 from 28 and we're left with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

On to step 3:
The number 15 fits into 135 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtract 135 from 135 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 15

Let's proceed to step 4:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 190.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 15

Let's proceed to step 5:
15 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1900.0
If we take 0 away from 10, we end up with 10.
Include the next digit (7) from the dividend after 10, then repeat: 107 / 15

Let's proceed to step 6:
When dividing 107 by 15, we get 7 with a remainder of 2.
The next digit of our result is 7. 
Result so far: 19007.0
Subtracting 105 from 107 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 15 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 19007.1
Subtract 15 from 20 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 19007.13
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 19007.133
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 19007.133 with a balance of 0.0005.
