Let's divide 108515 by 8
The aim is to understand the frequency of 8 in 108515.

Advancing to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 8

Going ahead to step 2:
If we divide 10 by 8, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 8 from 10 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 8

On to step 3:
28 divided by 8 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 24 from 28 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 8

Advancing to step 4:
The number 8 fits into 45 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 40 from 45 to get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 8

Step 5:
If we divide 51 by 8, we get 6 and a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 1356.0
Subtracting 48 from 51 leaves us with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 8

Advancing to step 6:
8 goes into 35 4 times with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 13564.0
The remainder is 3 after subtracting 32 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
When dividing 30 by 8, we get 3 with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 13564.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 13564.37
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
8 goes into 40 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 13564.375
Subtract 40 from 40 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 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13564.375
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.

Let's proceed to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 13564.375
Deduct 0 from 0 and we're left 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.

The final result is 13564.375 with a remainder of 0.0.
