We divide 166667 by 80
The aim is to understand the frequency of 80 in 166667.

On to step 1:
80 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 80

Let's proceed to step 2:
If we divide 16 by 80, we get 0 and a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 80

Going ahead to step 3:
80 goes into 166 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 160 from 166 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 80

Step 4:
80 can be fit into 66 0 times, resulting in a remainder of 66.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 66, we get 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 80

Step 5:
If we divide 666 by 80, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 208.0
Deduct 640 from 666 and we're left with 26.
Grab the next digit (7) from the dividend, add it to 26, then carry on: 267 / 80

Going ahead to step 6:
The number 80 fits into 267 3 times, leaving a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 2083.0
Subtract 240 from 267 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 7:
If we divide 270 by 80, we get 3 and a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 2083.3
Subtract 240 from 270 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
When dividing 300 by 80, we get 3 with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 2083.33
Deduct 240 from 300 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.

The final outcome is 2083.33, with a leftover of 0.06.
