660 divided by 8 
The aim is to understand the frequency of 8 in 660.

Let's proceed to step 1:
If we divide 6 by 8, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 8

Let's proceed to step 2:
66 divided by 8 is 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 64 away from 66, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 8

Let's proceed to step 3:
20 divided by 8 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 82.0
Subtract 16 from 20 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 4:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 82.5
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.

Moving on to step 5:
8 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 82.5
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.

Going ahead to step 6:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 82.5
Subtracting 0 from 0 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.

In conclusion, the division gives 82.5 with a balance of 0.0.
