285973 divided by 15 
We're looking to find how many times 15 goes into 285973.

Let's proceed to step 1:
If we divide 2 by 15, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 15

Moving on to step 2:
When dividing 28 by 15, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 15 from 28 to get 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 15

Moving on to step 3:
135 divided by 15 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
The remainder is 0 after subtracting 135 from 135.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 15

Advancing to step 4:
9 divided by 15 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 190.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 15

Advancing to step 5:
97 divided by 15 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 1906.0
If we take 90 away from 97, we end up with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 15

Going ahead to step 6:
If we divide 73 by 15, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 19064.0
Subtracting 60 from 73 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
15 goes into 130 8 times with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 19064.8
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.

On to step 8:
100 divided by 15 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 19064.86
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.

Going ahead to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 19064.866
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.

After the division, we end up with 19064.866 and a remainder of 0.001.
