We look at the division of 63360224 by 80 
The aim is to understand the frequency of 80 in 63360224.

On to step 1:
6 divided by 80 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 80

Advancing to step 2:
When dividing 63 by 80, we get 0 with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (3) from the dividend to 63 and continue with: 633 / 80

Moving on to step 3:
If we divide 633 by 80, we get 7 and a remainder of 73.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 560 from 633 leaves us with 73.
Include the next digit (6) from the dividend after 73, then repeat: 736 / 80

On to step 4:
80 goes into 736 9 times with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
If we subtract 720 from 736, we get 16.
Append the next digit (0) from the dividend to 16 and continue with: 160 / 80

Step 5:
80 goes into 160 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 792.0
The remainder is 0 after subtracting 160 from 160.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 80

Advancing to step 6:
2 divided by 80 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 7920.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 80

Moving on to step 7:
22 divided by 80 is 0 with a remainder of 22.
Record the quotient 0 as the next digit in the result. 
Result so far: 79200.0
Subtracting 0 from 22 leaves us with 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 80

Moving on to step 8:
80 can be fit into 224 2 times, resulting in a remainder of 64.
Put 2 as the next digit of the answer. 
Result so far: 792002.0
If we subtract 160 from 224, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 9:
640 divided by 80 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 792002.8
Subtracting 640 from 640 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 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 792002.8
Deduct 0 from 0 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.

On to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 792002.8
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.

The final outcome is 792002.8, with a leftover of 0.0.
