939656 ÷ 80 
The aim is to understand the frequency of 80 in 939656.

On to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 80

Let's proceed to step 2:
93 divided by 80 is 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 80 from 93 to get 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 80

Moving on to step 3:
80 can be fit into 139 1 times, resulting in a remainder of 59.
The next digit of our result is 1. 
Result so far: 11.0
The remainder is 59 after subtracting 80 from 139.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 80

Advancing to step 4:
596 divided by 80 is 7 with a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 117.0
Subtracting 560 from 596 leaves us with 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 80

Step 5:
80 goes into 365 4 times with a remainder of 45.
The number 4 becomes the next digit in our result. 
Result so far: 1174.0
Subtract 320 from 365 to get 45.
Include the next digit (6) from the dividend after 45, then repeat: 456 / 80

Going ahead to step 6:
If we divide 456 by 80, we get 5 and a remainder of 56.
Record the quotient 5 as the next digit in the result. 
Result so far: 11745.0
Subtract 400 from 456 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 7:
The number 80 fits into 560 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 11745.7
Subtracting 560 from 560 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.

Step 8:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11745.7
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 9:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 11745.7
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.

After the division, we end up with 11745.7 and a remainder of 0.0.
