We look at the division of 656347 by 80 
The aim is to understand the frequency of 80 in 656347.

Going ahead to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 80

Moving on to step 2:
80 can be fit into 65 0 times, resulting in a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Include the next digit (6) from the dividend after 65, then repeat: 656 / 80

Moving on to step 3:
80 goes into 656 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 640 from 656 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 80

Advancing to step 4:
If we divide 163 by 80, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 82.0
Deduct 160 from 163 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 80

Moving on to step 5:
When dividing 34 by 80, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 820.0
Subtracting 0 from 34 leaves us with 34.
Grab the next digit (7) from the dividend, add it to 34, then carry on: 347 / 80

Moving on to step 6:
When dividing 347 by 80, we get 4 with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 8204.0
Deduct 320 from 347 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
270 divided by 80 is 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 8204.3
If we take 240 away from 270, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 80 is 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 8204.33
If we subtract 240 from 300, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final outcome is 8204.33, with a leftover of 0.06.
