81212 ÷ 8 
The aim is to understand the frequency of 8 in 81212.

On to step 1:
8 can be fit into 8 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 8 away from 8, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 8

Moving on to step 2:
1 divided by 8 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Advancing to step 3:
The number 8 fits into 12 1 times, leaving a remainder of 4.
The next digit of our result is 1. 
Result so far: 101.0
The remainder is 4 after subtracting 8 from 12.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 8

Moving on to step 4:
8 goes into 41 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 1015.0
If we subtract 40 from 41, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 8

Moving on to step 5:
8 goes into 12 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 10151.0
Deduct 8 from 12 and we're left 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.

Let's proceed to step 6:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 10151.5
Subtracting 40 from 40 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.

Let's proceed to step 7:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10151.5
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 8:
8 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10151.5
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.

The quotient of the division is 10151.5, and the remainder is 0.0.
