Let's divide 70214984 by 8
The aim is to understand the frequency of 8 in 70214984.

Let's proceed to step 1:
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: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 8

Advancing to step 2:
70 divided by 8 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 64 away from 70, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 8

Advancing to step 3:
The number 8 fits into 62 7 times, leaving a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 87.0
Subtracting 56 from 62 leaves us with 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 8

Advancing to step 4:
The number 8 fits into 61 7 times, leaving a remainder of 5.
The next digit of our result is 7. 
Result so far: 877.0
Subtract 56 from 61 to get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 8

Let's proceed to step 5:
8 can be fit into 54 6 times, resulting in a remainder of 6.
The next digit of our result is 6. 
Result so far: 8776.0
The remainder is 6 after subtracting 48 from 54.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 8

Step 6:
If we divide 69 by 8, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 87768.0
Subtract 64 from 69 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 8

Moving on to step 7:
The number 8 fits into 58 7 times, leaving a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 877687.0
Deduct 56 from 58 and we're left with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 8

Moving on to step 8:
24 divided by 8 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 8776873.0
If we take 24 away from 24, 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.

Going ahead to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8776873.0
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 10:
If we divide 0 by 8, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8776873.0
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 outcome is 8776873.0, with a leftover of 0.0.
