We divide 69279 by 80
The aim is to understand the frequency of 80 in 69279.

On to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 80

Let's proceed to step 2:
80 goes into 69 0 times with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (2) of the dividend behind the 69 and repeat the process: 692 / 80

On to step 3:
692 divided by 80 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 640 away from 692, we end up with 52.
Fetch the next digit (7) from the dividend, attach it to 52 and continue: 527 / 80

Let's proceed to step 4:
527 divided by 80 is 6 with a remainder of 47.
Record the quotient 6 as the next digit in the result. 
Result so far: 86.0
The remainder is 47 after subtracting 480 from 527.
Bring next digit (9) of the dividend behind the 47 and repeat the process: 479 / 80

Moving on to step 5:
80 can be fit into 479 5 times, resulting in a remainder of 79.
The next digit of our result is 5. 
Result so far: 865.0
Subtracting 400 from 479 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 6:
790 divided by 80 is 9 with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 865.9
Subtract 720 from 790 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
80 goes into 700 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 865.98
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
When dividing 600 by 80, we get 7 with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 865.987
If we take 560 away from 600, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 865.9875
Deduct 400 from 400 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.

Moving on to step 10:
80 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: 865.9875
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.

On to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 865.9875
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.

After the division, we end up with 865.9875 and a remainder of 0.0.
