We're dividing 783330 by 80 
The aim is to understand the frequency of 80 in 783330.

On to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 80

Moving on to step 2:
80 goes into 78 0 times with a remainder of 78.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Grab the next digit (3) from the dividend, add it to 78, then carry on: 783 / 80

On to step 3:
783 divided by 80 is 9 with a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 720 from 783, we get 63.
Grab the next digit (3) from the dividend, add it to 63, then carry on: 633 / 80

Let's proceed to step 4:
633 divided by 80 is 7 with a remainder of 73.
Use 7 as the next digit of our solution. 
Result so far: 97.0
The remainder is 73 after subtracting 560 from 633.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 80

Advancing to step 5:
The number 80 fits into 733 9 times, leaving a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 979.0
Deduct 720 from 733 and we're left with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 80

Let's proceed to step 6:
80 goes into 130 1 times with a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 9791.0
If we take 80 away from 130, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
500 divided by 80 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 9791.6
If we subtract 480 from 500, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
80 goes into 200 2 times with a remainder of 40.
Write down 2 as next digit of the result. 
Result so far: 9791.62
Subtracting 160 from 200 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9791.625
Subtracting 400 from 400 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.

On to step 10:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9791.625
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.

Step 11:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9791.625
The remainder is 0 after subtracting 0 from 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 9791.625 with a remainder of 0.0.
