We're dividing 88661083 by 8 
The aim is to understand the frequency of 8 in 88661083.

Going ahead to step 1:
When dividing 8 by 8, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 8

Step 2:
The number 8 fits into 8 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 8

Moving on to step 3:
If we divide 6 by 8, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 8

Let's proceed to step 4:
If we divide 66 by 8, we get 8 and a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 1108.0
If we subtract 64 from 66, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 8

Advancing to step 5:
The number 8 fits into 21 2 times, leaving a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 11082.0
Deduct 16 from 21 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 8

Advancing to step 6:
If we divide 50 by 8, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 110826.0
Subtract 48 from 50 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 8

Going ahead to step 7:
When dividing 28 by 8, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 1108263.0
Subtracting 24 from 28 leaves us with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 8

Let's proceed to step 8:
8 goes into 43 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 11082635.0
Subtract 40 from 43 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
8 goes into 30 3 times with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 11082635.3
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 8 fits into 60 7 times, leaving a remainder of 4.
The next digit of our result is 7. 
Result so far: 11082635.37
If we subtract 56 from 60, 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.

Let's proceed to step 11:
40 divided by 8 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11082635.375
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.

Let's proceed to step 12:
If we divide 0 by 8, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11082635.375
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.

Moving on to step 13:
When dividing 0 by 8, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11082635.375
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.

After the division, we end up with 11082635.375 and a remainder of 0.0.
