We look at the division of 13993 by 15 
We want to divide 13993 by 15.

On to step 1:
1 divided by 15 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 15

Moving on to step 2:
13 divided by 15 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 15

On to step 3:
15 goes into 139 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 135 from 139 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 15

Advancing to step 4:
15 can be fit into 49 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 93.0
If we take 45 away from 49, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 15

Step 5:
15 goes into 43 2 times with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 932.0
If we take 30 away from 43, we end up 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.

Going ahead to step 6:
The number 15 fits into 130 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 932.8
Subtract 120 from 130 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 7:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 932.86
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 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 932.866
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.

In conclusion, the division gives 932.866 with a balance of 0.001.
