We look at the division of 667164 by 80 
The aim is to understand the frequency of 80 in 667164.

Moving on to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 80

Let's proceed to step 2:
When dividing 66 by 80, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (7) from the dividend and append it to 66, then repeat: 667 / 80

Step 3:
If we divide 667 by 80, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 640 from 667 to get 27.
Take the next digit (1) from the dividend and append it to 27, then repeat: 271 / 80

Going ahead to step 4:
When dividing 271 by 80, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 83.0
Subtracting 240 from 271 leaves us with 31.
Bring next digit (6) of the dividend behind the 31 and repeat the process: 316 / 80

Moving on to step 5:
The number 80 fits into 316 3 times, leaving a remainder of 76.
Put 3 as the next digit of the answer. 
Result so far: 833.0
Subtracting 240 from 316 leaves us with 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 80

Step 6:
If we divide 764 by 80, we get 9 and a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 8339.0
If we subtract 720 from 764, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
80 goes into 440 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 8339.5
Deduct 400 from 440 and we're left 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.

Let's proceed to step 8:
400 divided by 80 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8339.55
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.

The final result is 8339.55 with a remainder of 0.0.
