We look at the division of 313597 by 15 
We want to divide 313597 by 15.

Step 1:
3 divided by 15 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Let's proceed to step 2:
31 divided by 15 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 30 from 31 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 15

Going ahead to step 3:
If we divide 13 by 15, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 13 to get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 15

Going ahead to step 4:
If we divide 135 by 15, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
If we subtract 135 from 135, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 15

Advancing to step 5:
If we divide 9 by 15, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 2090.0
Subtract 0 from 9 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 15

Going ahead to step 6:
97 divided by 15 is 6 with a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 20906.0
Subtracting 90 from 97 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:
70 divided by 15 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 20906.4
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.

Step 8:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 20906.46
Subtracting 90 from 100 leaves us 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.

Step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 20906.466
Subtracting 90 from 100 leaves us 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 20906.466 with a balance of 0.001.
