Let's divide 245422 by 80
The aim is to understand the frequency of 80 in 245422.

Advancing 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
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 80

Going ahead to step 2:
80 can be fit into 24 0 times, resulting in a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 80

Moving on to step 3:
If we divide 245 by 80, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 240 from 245, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 80

Let's proceed to step 4:
80 can be fit into 54 0 times, resulting in a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 54 and we're left with 54.
Take the next digit (2) from the dividend and append it to 54, then repeat: 542 / 80

Moving on to step 5:
80 goes into 542 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
If we subtract 480 from 542, we get 62.
Take the next digit (2) from the dividend and append it to 62, then repeat: 622 / 80

Step 6:
If we divide 622 by 80, we get 7 and a remainder of 62.
The next digit of our result is 7. 
Result so far: 3067.0
If we take 560 away from 622, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
80 goes into 620 7 times with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 3067.7
If we take 560 away from 620, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 3067.77
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.

The quotient of the division is 3067.77, and the remainder is 0.04.
