We look at the division of 121212 by 8 
The aim is to understand the frequency of 8 in 121212.

Going ahead to step 1:
When dividing 1 by 8, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

Let's proceed to step 2:
If we divide 12 by 8, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 8 from 12 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 8

Advancing to step 3:
The number 8 fits into 41 5 times, leaving a remainder of 1.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 1 after subtracting 40 from 41.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

Let's proceed to step 4:
8 can be fit into 12 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 4 after subtracting 8 from 12.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 8

Step 5:
41 divided by 8 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1515.0
If we subtract 40 from 41, we get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

Let's proceed to step 6:
The number 8 fits into 12 1 times, leaving a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 15151.0
If we subtract 8 from 12, we 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.

Advancing to step 7:
When dividing 40 by 8, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 15151.5
The remainder is 0 after subtracting 40 from 40.
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 8:
When dividing 0 by 8, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15151.5
Subtract 0 from 0 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.

Let's proceed to step 9:
8 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15151.5
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.

Our division results in 15151.5 with a remaining 0.0.
