We divide 22663804 by 80
The aim is to understand the frequency of 80 in 22663804.

Step 1:
2 divided by 80 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
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

Going ahead to step 2:
If we divide 22 by 80, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 80

Moving on to step 3:
If we divide 226 by 80, we get 2 and a remainder of 66.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 160 from 226 and we're left with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 80

Advancing to step 4:
If we divide 666 by 80, we get 8 and a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 26 after subtracting 640 from 666.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 80

Let's proceed to step 5:
The number 80 fits into 263 3 times, leaving a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 283.0
If we take 240 away from 263, we end up with 23.
Take the next digit (8) from the dividend and append it to 23, then repeat: 238 / 80

Let's proceed to step 6:
The number 80 fits into 238 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 2832.0
Deduct 160 from 238 and we're left with 78.
Take the next digit (0) from the dividend and append it to 78, then repeat: 780 / 80

Step 7:
80 goes into 780 9 times with a remainder of 60.
Write down 9 as next digit of the result. 
Result so far: 28329.0
If we subtract 720 from 780, we get 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 80

Moving on to step 8:
The number 80 fits into 604 7 times, leaving a remainder of 44.
The next digit of our result is 7. 
Result so far: 283297.0
Subtracting 560 from 604 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 9:
80 goes into 440 5 times with a remainder of 40.
The next digit of our result is 5. 
Result so far: 283297.5
If we take 400 away from 440, 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.

Moving on to 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: 283297.55
Subtract 400 from 400 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 283297.55 and a remainder of 0.0.
