727825 divided by 80 
The aim is to understand the frequency of 80 in 727825.

Step 1:
80 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 80

Advancing to step 2:
If we divide 72 by 80, we get 0 and a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 72 leaves us with 72.
Include the next digit (7) from the dividend after 72, then repeat: 727 / 80

On to step 3:
727 divided by 80 is 9 with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 720 away from 727, we end up with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 80

Step 4:
80 goes into 78 0 times with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 90.0
Subtract 0 from 78 to get 78.
Bring next digit (2) of the dividend behind the 78 and repeat the process: 782 / 80

Going ahead to step 5:
If we divide 782 by 80, we get 9 and a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 909.0
Subtract 720 from 782 to get 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 80

Going ahead to step 6:
When dividing 625 by 80, we get 7 with a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 9097.0
Deduct 560 from 625 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
650 divided by 80 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 9097.8
If we take 640 away from 650, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 80, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 9097.81
Subtracting 80 from 100 leaves us with 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 9:
If we divide 200 by 80, we get 2 and a remainder of 40.
The next digit of our result is 2. 
Result so far: 9097.812
If we subtract 160 from 200, 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.

Step 10:
400 divided by 80 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9097.8125
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 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9097.8125
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.

Going ahead to step 12:
80 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 9097.8125
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.

The final outcome is 9097.8125, with a leftover of 0.0.
