168717 ÷ 15 
The aim is to understand the frequency of 15 in 168717.

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
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 15

Moving on to step 2:
15 can be fit into 16 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 15 away from 16, we end up with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 15

Going ahead to step 3:
When dividing 18 by 15, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 3 after subtracting 15 from 18.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 15

Going ahead to step 4:
37 divided by 15 is 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 112.0
Deduct 30 from 37 and we're left with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 15

Advancing to step 5:
The number 15 fits into 71 4 times, leaving a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 1124.0
If we subtract 60 from 71, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 15

Moving on to step 6:
The number 15 fits into 117 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 11247.0
Deduct 105 from 117 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
The number 15 fits into 120 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 11247.8
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11247.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11247.8
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 11247.8 with a balance of 0.0.
