Let's divide 219573 by 80
The aim is to understand the frequency of 80 in 219573.

Let's proceed to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Write down 0 as next digit of 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

Moving on to step 2:
80 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 80

On to step 3:
219 divided by 80 is 2 with a remainder of 59.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 59 after subtracting 160 from 219.
Take the next digit (5) from the dividend and append it to 59, then repeat: 595 / 80

Advancing to step 4:
80 can be fit into 595 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 27.0
If we take 560 away from 595, we end up with 35.
Take the next digit (7) from the dividend and append it to 35, then repeat: 357 / 80

Let's proceed to step 5:
357 divided by 80 is 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 274.0
Deduct 320 from 357 and we're left with 37.
Grab the next digit (3) from the dividend, add it to 37, then carry on: 373 / 80

Step 6:
80 goes into 373 4 times with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 2744.0
If we take 320 away from 373, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
When dividing 530 by 80, we get 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 2744.6
Subtract 480 from 530 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 8:
When dividing 500 by 80, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 2744.66
Deduct 480 from 500 and we're left 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.

The final result is 2744.66 with a remainder of 0.02.
