We're dividing 79920 by 80 
The aim is to understand the frequency of 80 in 79920.

Advancing to step 1:
80 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 80

Going ahead to step 2:
80 can be fit into 79 0 times, resulting in a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Take the next digit (9) from the dividend and append it to 79, then repeat: 799 / 80

Going ahead to step 3:
80 can be fit into 799 9 times, resulting in a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 79 after subtracting 720 from 799.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 80

Advancing to step 4:
When dividing 792 by 80, we get 9 with a remainder of 72.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 720 from 792 to get 72.
Take the next digit (0) from the dividend and append it to 72, then repeat: 720 / 80

Let's proceed to step 5:
80 can be fit into 720 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
If we subtract 720 from 720, we 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 6:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 999.0
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 7:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 999.0
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.

In conclusion, the division gives 999.0 with a balance of 0.0.
