427534 divided by 80 
The aim is to understand the frequency of 80 in 427534.

Moving on to step 1:
4 divided by 80 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 80

Let's proceed to step 2:
42 divided by 80 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Grab the next digit (7) from the dividend, add it to 42, then carry on: 427 / 80

Going ahead to step 3:
427 divided by 80 is 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 400 away from 427, we end up with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 80

Step 4:
80 goes into 275 3 times with a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
Subtract 240 from 275 to get 35.
Take the next digit (3) from the dividend and append it to 35, then repeat: 353 / 80

Let's proceed to step 5:
353 divided by 80 is 4 with a remainder of 33.
Put 4 as the next digit of the answer. 
Result so far: 534.0
Subtracting 320 from 353 leaves us with 33.
Grab the next digit (4) from the dividend, add it to 33, then carry on: 334 / 80

Going ahead to step 6:
The number 80 fits into 334 4 times, leaving a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 5344.0
The remainder is 14 after subtracting 320 from 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
If we divide 140 by 80, we get 1 and a remainder of 60.
The next digit of our result is 1. 
Result so far: 5344.1
If we take 80 away from 140, 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.

Going ahead to step 8:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 5344.17
Subtract 560 from 600 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5344.175
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5344.175
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.

Advancing to step 11:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5344.175
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.

Our division results in 5344.175 with a remaining 0.0.
