Let's divide 655187 by 80
The aim is to understand the frequency of 80 in 655187.

On to step 1:
6 divided by 80 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 80

On to step 2:
80 can be fit into 65 0 times, resulting in a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 80

Step 3:
When dividing 655 by 80, we get 8 with a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 15 after subtracting 640 from 655.
Fetch the next digit (1) from the dividend, attach it to 15 and continue: 151 / 80

Going ahead to step 4:
80 goes into 151 1 times with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 81.0
Subtracting 80 from 151 leaves us with 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 80

Going ahead to step 5:
80 goes into 718 8 times with a remainder of 78.
The next digit of our result is 8. 
Result so far: 818.0
Deduct 640 from 718 and we're left with 78.
Include the next digit (7) from the dividend after 78, then repeat: 787 / 80

Let's proceed to step 6:
When dividing 787 by 80, we get 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 8189.0
If we take 720 away from 787, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 7:
The number 80 fits into 670 8 times, leaving a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 8189.8
Subtract 640 from 670 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
If we divide 300 by 80, we get 3 and a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 8189.83
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 9:
If we divide 600 by 80, we get 7 and a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 8189.837
If we take 560 away from 600, we end up 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.

Step 10:
When dividing 400 by 80, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 8189.8375
If we subtract 400 from 400, 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.

Step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8189.8375
Deduct 0 from 0 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.

Advancing to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 8189.8375
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.

After the division, we end up with 8189.8375 and a remainder of 0.0.
