285686 divided by 15 
We want to divide 285686 by 15.

Step 1:
15 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 15

Advancing to step 2:
If we divide 28 by 15, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 15 from 28 leaves us with 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 15

On to step 3:
When dividing 135 by 15, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Subtracting 135 from 135 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 15

Let's proceed to step 4:
6 divided by 15 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 15

Moving on to step 5:
15 can be fit into 68 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1904.0
Subtract 60 from 68 to get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 15

Let's proceed to step 6:
86 divided by 15 is 5 with a remainder of 11.
Record the quotient 5 as the next digit in the result. 
Result so far: 19045.0
Subtracting 75 from 86 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
The number 15 fits into 110 7 times, leaving a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 19045.7
Deduct 105 from 110 and we're left 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.

Going ahead to step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 19045.73
Subtract 45 from 50 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 9:
50 divided by 15 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 19045.733
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.

The final result is 19045.733 with a remainder of 0.0005.
