We look at the division of 315082 by 15 
We want to figure out the number of times 315082 can be divided by 15.

Let's proceed to step 1:
15 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 15

Let's proceed to step 2:
15 can be fit into 31 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 30 from 31 and we're left with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 15

Moving on to step 3:
The number 15 fits into 15 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Deduct 15 from 15 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 15

Let's proceed to step 4:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 210.0
If we subtract 0 from 0, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 15

Let's proceed to step 5:
If we divide 8 by 15, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 2100.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 15

Step 6:
When dividing 82 by 15, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 21005.0
Subtracting 75 from 82 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 21005.4
Deduct 60 from 70 and we're left 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 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 21005.46
Subtract 90 from 100 to get 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:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 21005.466
Subtract 90 from 100 to get 10.
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 21005.466 and a remainder of 0.001.
