We're looking to find how many times 15 goes into 192815.

Going ahead to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 15

Moving on to step 2:
The number 15 fits into 19 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 15 from 19.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 15

Going ahead to step 3:
42 divided by 15 is 2 with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 30 from 42 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 15

Step 4:
128 divided by 15 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 120 from 128 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 15

Advancing to step 5:
81 divided by 15 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 1285.0
Subtracting 75 from 81 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 15

Moving on to step 6:
15 goes into 65 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 12854.0
The remainder is 5 after subtracting 60 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 12854.3
The remainder is 5 after subtracting 45 from 50.
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 8:
15 goes into 50 3 times with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 12854.33
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.

The final result is 12854.33 with a remainder of 0.005.
