548524 divided by 80 
The aim is to understand the frequency of 80 in 548524.

Going ahead to step 1:
80 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 80

Step 2:
The number 80 fits into 54 0 times, leaving a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 54, we get 54.
Fetch the next digit (8) from the dividend, attach it to 54 and continue: 548 / 80

On to step 3:
80 goes into 548 6 times with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 480 from 548, we get 68.
Append the next digit (5) from the dividend to 68 and continue with: 685 / 80

Advancing to step 4:
80 goes into 685 8 times with a remainder of 45.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
Subtracting 640 from 685 leaves us with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 80

Moving on to step 5:
80 can be fit into 452 5 times, resulting in a remainder of 52.
The next digit of our result is 5. 
Result so far: 685.0
If we subtract 400 from 452, we get 52.
Include the next digit (4) from the dividend after 52, then repeat: 524 / 80

Step 6:
The number 80 fits into 524 6 times, leaving a remainder of 44.
The next digit of our result is 6. 
Result so far: 6856.0
If we subtract 480 from 524, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 7:
80 goes into 440 5 times with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 6856.5
If we subtract 400 from 440, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6856.55
Deduct 400 from 400 and we're left 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.

Our division results in 6856.55 with a remaining 0.0.
