We look at the division of 860765 by 80 
The aim is to understand the frequency of 80 in 860765.

Let's proceed to step 1:
8 divided by 80 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 80

Step 2:
The number 80 fits into 86 1 times, leaving a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 80 from 86.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 80

Advancing to step 3:
80 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 60, we end up with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 80

Advancing to step 4:
If we divide 607 by 80, we get 7 and a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 107.0
If we subtract 560 from 607, we get 47.
Take the next digit (6) from the dividend and append it to 47, then repeat: 476 / 80

Moving on to step 5:
When dividing 476 by 80, we get 5 with a remainder of 76.
Record the quotient 5 as the next digit in the result. 
Result so far: 1075.0
The remainder is 76 after subtracting 400 from 476.
Bring next digit (5) of the dividend behind the 76 and repeat the process: 765 / 80

Advancing to step 6:
80 goes into 765 9 times with a remainder of 45.
The next digit of our result is 9. 
Result so far: 10759.0
Subtracting 720 from 765 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
450 divided by 80 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 10759.5
If we subtract 400 from 450, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 8:
500 divided by 80 is 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 10759.56
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.

Step 9:
80 goes into 200 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 10759.562
Deduct 160 from 200 and we're left 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.

Advancing to step 10:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 10759.5625
The remainder is 0 after subtracting 400 from 400.
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10759.5625
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.

Moving on to step 12:
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: 10759.5625
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 10759.5625 with a remainder of 0.0.
