We're dividing 123412 by 8 
The aim is to understand the frequency of 8 in 123412.

Step 1:
8 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
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 8

Advancing to step 2:
When dividing 12 by 8, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 8 from 12, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 8

On to step 3:
43 divided by 8 is 5 with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 3 after subtracting 40 from 43.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 8

On to step 4:
8 can be fit into 34 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 154.0
If we take 32 away from 34, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 8

Let's proceed to step 5:
When dividing 21 by 8, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 1542.0
If we subtract 16 from 21, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 8

Let's proceed to step 6:
When dividing 52 by 8, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 15426.0
Subtracting 48 from 52 leaves us with 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 7:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 15426.5
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.

Let's proceed to step 8:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15426.5
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.

On to step 9:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15426.5
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.

In conclusion, the division gives 15426.5 with a balance of 0.0.
