Let's divide 99650379 by 8
The aim is to understand the frequency of 8 in 99650379.

Let's proceed to step 1:
If we divide 9 by 8, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 8 from 9 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 8

Step 2:
8 can be fit into 19 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 16 from 19 to get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 8

Moving on to step 3:
36 divided by 8 is 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
If we subtract 32 from 36, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 8

Moving on to step 4:
If we divide 45 by 8, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1245.0
Subtracting 40 from 45 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 8

Moving on to step 5:
When dividing 50 by 8, we get 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 12456.0
If we take 48 away from 50, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 8

Step 6:
The number 8 fits into 23 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 124562.0
If we take 16 away from 23, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 8

Step 7:
If we divide 77 by 8, we get 9 and a remainder of 5.
The next digit of our result is 9. 
Result so far: 1245629.0
The remainder is 5 after subtracting 72 from 77.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 8

Advancing to step 8:
If we divide 59 by 8, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 12456297.0
If we subtract 56 from 59, we 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.

Moving on to step 9:
The number 8 fits into 30 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 12456297.3
If we subtract 24 from 30, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
8 can be fit into 60 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 12456297.37
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.

Going ahead to step 11:
If we divide 40 by 8, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12456297.375
The remainder is 0 after subtracting 40 from 40.
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:
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: 12456297.375
The remainder is 0 after subtracting 0 from 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 13:
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: 12456297.375
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.

The final result is 12456297.375 with a remainder of 0.0.
