We're dividing 955173 by 80 
The aim is to understand the frequency of 80 in 955173.

Moving on to step 1:
If we divide 9 by 80, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 80

On to step 2:
80 goes into 95 1 times with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 15 after subtracting 80 from 95.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 80

Advancing to step 3:
If we divide 155 by 80, we get 1 and a remainder of 75.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 80 from 155 leaves us with 75.
Fetch the next digit (1) from the dividend, attach it to 75 and continue: 751 / 80

Step 4:
When dividing 751 by 80, we get 9 with a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we take 720 away from 751, we end up with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 80

Going ahead to step 5:
When dividing 317 by 80, we get 3 with a remainder of 77.
The next digit of our result is 3. 
Result so far: 1193.0
If we subtract 240 from 317, we get 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 80

Let's proceed to step 6:
773 divided by 80 is 9 with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 11939.0
The remainder is 53 after subtracting 720 from 773.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
530 divided by 80 is 6 with a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 11939.6
Deduct 480 from 530 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 8:
80 can be fit into 500 6 times, resulting in a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 11939.66
Subtracting 480 from 500 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.

After the division, we end up with 11939.66 and a remainder of 0.02.
