We look at the division of 627398 by 80 
The aim is to understand the frequency of 80 in 627398.

Going ahead to step 1:
80 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 80

On to step 2:
If we divide 62 by 80, we get 0 and a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 62 and we're left with 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 80

Let's proceed to step 3:
When dividing 627 by 80, we get 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 560 from 627, we get 67.
Include the next digit (3) from the dividend after 67, then repeat: 673 / 80

Step 4:
80 can be fit into 673 8 times, resulting in a remainder of 33.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtracting 640 from 673 leaves us with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 80

Let's proceed to step 5:
80 goes into 339 4 times with a remainder of 19.
The next digit of our result is 4. 
Result so far: 784.0
Subtracting 320 from 339 leaves us with 19.
Append the next digit (8) from the dividend to 19 and continue with: 198 / 80

On to step 6:
If we divide 198 by 80, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 7842.0
Deduct 160 from 198 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 7:
380 divided by 80 is 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 7842.4
Deduct 320 from 380 and we're left 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.

On to step 8:
600 divided by 80 is 7 with a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 7842.47
Deduct 560 from 600 and we're left 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.

Going ahead to step 9:
When dividing 400 by 80, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 7842.475
If we take 400 away from 400, we end up 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.

Going ahead to step 10:
0 divided by 80 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7842.475
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 7842.475
Subtracting 0 from 0 leaves us 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.

Our division results in 7842.475 with a remaining 0.0.
