We're dividing 606618 by 80 
The aim is to understand the frequency of 80 in 606618.

Going ahead to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 80

Moving on to step 2:
60 divided by 80 is 0 with a remainder of 60.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 60 after subtracting 0 from 60.
Append the next digit (6) from the dividend to 60 and continue with: 606 / 80

Step 3:
606 divided by 80 is 7 with a remainder of 46.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 560 from 606 and we're left with 46.
Grab the next digit (6) from the dividend, add it to 46, then carry on: 466 / 80

Let's proceed to step 4:
466 divided by 80 is 5 with a remainder of 66.
Put 5 as the next digit of the answer. 
Result so far: 75.0
Subtracting 400 from 466 leaves us with 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 80

Advancing to step 5:
The number 80 fits into 661 8 times, leaving a remainder of 21.
The next digit of our result is 8. 
Result so far: 758.0
Subtracting 640 from 661 leaves us with 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 80

Let's proceed to step 6:
The number 80 fits into 218 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 7582.0
If we subtract 160 from 218, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 7:
The number 80 fits into 580 7 times, leaving a remainder of 20.
Write down 7 as next digit of the result. 
Result so far: 7582.7
If we subtract 560 from 580, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 7582.72
Deduct 160 from 200 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.

Moving on to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 7582.725
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.

Moving on to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7582.725
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.

On to step 11:
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: 7582.725
If we take 0 away from 0, 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.

The final outcome is 7582.725, with a leftover of 0.0.
