We're dividing 218223 by 80 
The aim is to understand the frequency of 80 in 218223.

Going ahead to step 1:
2 divided by 80 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 80

Step 2:
The number 80 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 80

Step 3:
80 can be fit into 218 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 160 from 218 leaves us with 58.
Take the next digit (2) from the dividend and append it to 58, then repeat: 582 / 80

Step 4:
The number 80 fits into 582 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 560 away from 582, we end up with 22.
Bring next digit (2) of the dividend behind the 22 and repeat the process: 222 / 80

Let's proceed to step 5:
80 can be fit into 222 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 272.0
The remainder is 62 after subtracting 160 from 222.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 80

Advancing to step 6:
If we divide 623 by 80, we get 7 and a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 2727.0
The remainder is 63 after subtracting 560 from 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 7:
The number 80 fits into 630 7 times, leaving a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 2727.7
If we subtract 560 from 630, 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.

On to step 8:
80 goes into 700 8 times with a remainder of 60.
The next digit of our result is 8. 
Result so far: 2727.78
The remainder is 60 after subtracting 640 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
Record the quotient 7 as the next digit in the result. 
Result so far: 2727.787
Deduct 560 from 600 and we're left 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.

Going ahead to step 10:
80 goes into 400 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2727.7875
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:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2727.7875
If we take 0 away from 0, we end up 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.
Use 0 as the next digit of our solution. 
Result so far: 2727.7875
If we subtract 0 from 0, 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.

The final result is 2727.7875 with a remainder of 0.0.
