We're dividing 135728 by 80 
The aim is to understand the frequency of 80 in 135728.

Advancing to step 1:
When dividing 1 by 80, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 80

On to step 2:
13 divided by 80 is 0 with a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 80

On to step 3:
80 goes into 135 1 times with a remainder of 55.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 135, we get 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 80

Moving on to step 4:
557 divided by 80 is 6 with a remainder of 77.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 480 from 557 leaves us with 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 80

Step 5:
772 divided by 80 is 9 with a remainder of 52.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Deduct 720 from 772 and we're left with 52.
Grab the next digit (8) from the dividend, add it to 52, then carry on: 528 / 80

Advancing to step 6:
If we divide 528 by 80, we get 6 and a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1696.0
Subtract 480 from 528 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 7:
If we divide 480 by 80, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 1696.6
Subtract 480 from 480 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.

On to step 8:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1696.6
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.

On 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: 1696.6
If we subtract 0 from 0, 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.

The final outcome is 1696.6, with a leftover of 0.0.
