We're dividing 675591 by 80 
The aim is to understand the frequency of 80 in 675591.

Moving on to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 80

Going ahead to step 2:
80 can be fit into 67 0 times, resulting in a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Append the next digit (5) from the dividend to 67 and continue with: 675 / 80

Advancing to step 3:
If we divide 675 by 80, we get 8 and a remainder of 35.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 640 away from 675, we end up with 35.
Append the next digit (5) from the dividend to 35 and continue with: 355 / 80

On to step 4:
355 divided by 80 is 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 320 from 355, we get 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 80

Let's proceed to step 5:
The number 80 fits into 359 4 times, leaving a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 844.0
If we take 320 away from 359, we end up with 39.
Take the next digit (1) from the dividend and append it to 39, then repeat: 391 / 80

On to step 6:
If we divide 391 by 80, we get 4 and a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 8444.0
Subtracting 320 from 391 leaves us with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 7:
80 goes into 710 8 times with a remainder of 70.
The next digit of our result is 8. 
Result so far: 8444.8
If we subtract 640 from 710, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 8:
700 divided by 80 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 8444.88
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

In conclusion, the division gives 8444.88 with a balance of 0.06.
