57712 divided by 80 
The aim is to understand the frequency of 80 in 57712.

On to step 1:
5 divided by 80 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 80

On to step 2:
80 can be fit into 57 0 times, resulting in a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Include the next digit (7) from the dividend after 57, then repeat: 577 / 80

Advancing to step 3:
80 can be fit into 577 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 560 from 577 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 80

Moving on to step 4:
The number 80 fits into 171 2 times, leaving a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 72.0
Subtract 160 from 171 to get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 80

On to step 5:
If we divide 112 by 80, we get 1 and a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 721.0
If we take 80 away from 112, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 6:
320 divided by 80 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 721.4
The remainder is 0 after subtracting 320 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 721.4
If we take 0 away from 0, we end up 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.

On to step 8:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 721.4
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 result is 721.4 with a remainder of 0.0.
