We're dividing 85067 by 81 
The aim is to understand the frequency of 81 in 85067.

Step 1:
81 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 81

Let's proceed to step 2:
81 can be fit into 85 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 4 after subtracting 81 from 85.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 81

Going ahead to step 3:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 40 to get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 81

On to step 4:
81 goes into 406 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 105.0
If we take 405 away from 406, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 81

On to step 5:
If we divide 17 by 81, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 1050.0
The remainder is 17 after subtracting 0 from 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 6:
The number 81 fits into 170 2 times, leaving a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 1050.2
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 81 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 1050.2
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
800 divided by 81 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 1050.209
If we take 729 away from 800, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 9:
If we divide 710 by 81, we get 8 and a remainder of 62.
Record the quotient 8 as the next digit in the result. 
Result so far: 1050.2098
The remainder is 62 after subtracting 648 from 710.
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 10:
620 divided by 81 is 7 with a remainder of 53.
The next digit of our result is 7. 
Result so far: 1050.20987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 11:
When dividing 530 by 81, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 1050.209876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 1050.2098765
Subtract 405 from 440 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 13:
81 goes into 350 4 times with a remainder of 26.
The number 4 becomes the next digit in our result. 
Result so far: 1050.20987654
The remainder is 26 after subtracting 324 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Our division results in 1050.20987654 with a remaining 2.6e-08.
