We're dividing 22603187 by 80 
The aim is to understand the frequency of 80 in 22603187.

On to step 1:
When dividing 2 by 80, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 80

Step 2:
When dividing 22 by 80, we get 0 with a remainder of 22.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 80

On to step 3:
If we divide 226 by 80, we get 2 and a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 160 from 226 to get 66.
Take the next digit (0) from the dividend and append it to 66, then repeat: 660 / 80

Advancing to step 4:
660 divided by 80 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 28.0
If we take 640 away from 660, we end up with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 80

Let's proceed to step 5:
If we divide 203 by 80, we get 2 and a remainder of 43.
Write down 2 as next digit of the result. 
Result so far: 282.0
If we take 160 away from 203, we end up with 43.
Bring next digit (1) of the dividend behind the 43 and repeat the process: 431 / 80

Going ahead to step 6:
80 can be fit into 431 5 times, resulting in a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 2825.0
Subtract 400 from 431 to get 31.
Append the next digit (8) from the dividend to 31 and continue with: 318 / 80

Advancing to step 7:
When dividing 318 by 80, we get 3 with a remainder of 78.
The number 3 becomes the next digit in our result. 
Result so far: 28253.0
The remainder is 78 after subtracting 240 from 318.
Append the next digit (7) from the dividend to 78 and continue with: 787 / 80

Advancing to step 8:
If we divide 787 by 80, we get 9 and a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 282539.0
Subtracting 720 from 787 leaves us 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.

Advancing to step 9:
80 goes into 670 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 282539.8
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.

Going ahead to step 10:
300 divided by 80 is 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 282539.83
The remainder is 60 after subtracting 240 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
80 can be fit into 600 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 282539.837
The remainder is 40 after subtracting 560 from 600.
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 12:
When dividing 400 by 80, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 282539.8375
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 13:
When dividing 0 by 80, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 282539.8375
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.

Step 14:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 282539.8375
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.

The final outcome is 282539.8375, with a leftover of 0.0.
