121255 ÷ 8 
The aim is to understand the frequency of 8 in 121255.

Moving on to step 1:
If we divide 1 by 8, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 8

Advancing to step 2:
If we divide 12 by 8, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 8 from 12.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 8

Going ahead to step 3:
The number 8 fits into 41 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 40 from 41 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 8

Going ahead to step 4:
The number 8 fits into 12 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 151.0
Subtracting 8 from 12 leaves us with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 8

Step 5:
45 divided by 8 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1515.0
If we subtract 40 from 45, we get 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 8

Step 6:
When dividing 55 by 8, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 15156.0
The remainder is 7 after subtracting 48 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
8 can be fit into 70 8 times, resulting in a remainder of 6.
The next digit of our result is 8. 
Result so far: 15156.8
The remainder is 6 after subtracting 64 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on 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: 15156.87
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15156.875
If we subtract 40 from 40, we 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.

Advancing to step 10:
8 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15156.875
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.

Step 11:
If we divide 0 by 8, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15156.875
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 15156.875 with a balance of 0.0.
