We look at the division of 579432 by 80 
The aim is to understand the frequency of 80 in 579432.

Moving on to step 1:
80 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 80

Step 2:
80 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Append the next digit (9) from the dividend to 57 and continue with: 579 / 80

Going ahead to step 3:
When dividing 579 by 80, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 19 after subtracting 560 from 579.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 80

Moving on to step 4:
194 divided by 80 is 2 with a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 160 from 194 and we're left with 34.
Bring next digit (3) of the dividend behind the 34 and repeat the process: 343 / 80

Let's proceed to step 5:
343 divided by 80 is 4 with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 724.0
If we subtract 320 from 343, we get 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 80

Moving on to step 6:
232 divided by 80 is 2 with a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 7242.0
Deduct 160 from 232 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 7:
80 goes into 720 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 7242.9
The remainder is 0 after subtracting 720 from 720.
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 8:
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: 7242.9
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.

Going ahead to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7242.9
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.

The final outcome is 7242.9, with a leftover of 0.0.
