Let's divide 70312392 by 8
The aim is to understand the frequency of 8 in 70312392.

Going ahead to step 1:
8 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 8

Let's proceed to step 2:
When dividing 70 by 8, we get 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 64 from 70 to get 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 8

Moving on to step 3:
If we divide 63 by 8, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 87.0
Deduct 56 from 63 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 8

Advancing to step 4:
If we divide 71 by 8, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 878.0
The remainder is 7 after subtracting 64 from 71.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

Advancing to step 5:
8 goes into 72 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 8789.0
Subtract 72 from 72 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 8

Let's proceed to step 6:
3 divided by 8 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 87890.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 8

Going ahead to step 7:
39 divided by 8 is 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 878904.0
Deduct 32 from 39 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

Advancing to step 8:
If we divide 72 by 8, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 8789049.0
Subtract 72 from 72 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.

Step 9:
8 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8789049.0
If we take 0 away from 0, we end up 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 10:
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: 8789049.0
If we take 0 away from 0, we end up 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 8789049.0 with a remainder of 0.0.
