We look at the division of 99516087 by 8 
The aim is to understand the frequency of 8 in 99516087.

Advancing to step 1:
8 can be fit into 9 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
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.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 16 from 19, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 8

Moving on to step 3:
35 divided by 8 is 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 124.0
Subtract 32 from 35 to get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 8

Going ahead to step 4:
If we divide 31 by 8, we get 3 and a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 1243.0
If we subtract 24 from 31, we get 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 8

Step 5:
The number 8 fits into 76 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 12439.0
If we take 72 away from 76, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 8

On to step 6:
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: 124395.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 8

Going ahead to step 7:
8 divided by 8 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1243951.0
If we subtract 8 from 8, we get 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 8

Moving on to step 8:
The number 8 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 12439510.0
The remainder is 7 after subtracting 0 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 8, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 12439510.8
Deduct 64 from 70 and we're left with 6.
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 10:
8 goes into 60 7 times with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 12439510.87
If we take 56 away from 60, we end up 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 11:
8 goes into 40 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 12439510.875
Deduct 40 from 40 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 12:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12439510.875
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.

Let's proceed to step 13:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12439510.875
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.

Our division results in 12439510.875 with a remaining 0.0.
