We divide 63968520 by 8
The aim is to understand the frequency of 8 in 63968520.

Moving on to step 1:
8 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 8

Going ahead to step 2:
63 divided by 8 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 7.0
If we take 56 away from 63, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 8

Moving on to step 3:
When dividing 79 by 8, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtracting 72 from 79 leaves us with 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 8

Moving on to step 4:
If we divide 76 by 8, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 799.0
If we take 72 away from 76, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 8

Advancing to step 5:
The number 8 fits into 48 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 7996.0
If we subtract 48 from 48, we get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 8

Step 6:
5 divided by 8 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 79960.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 8

Step 7:
If we divide 52 by 8, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 799606.0
If we take 48 away from 52, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 8

Let's proceed to step 8:
If we divide 40 by 8, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 7996065.0
Subtracting 40 from 40 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.

On to step 9:
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: 7996065.0
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.

Going ahead to step 10:
8 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7996065.0
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 7996065.0, with a leftover of 0.0.
