65222 ÷ 81 
The aim is to understand the frequency of 81 in 65222.

Moving on to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 81

Step 2:
When dividing 65 by 81, we get 0 with a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (2) of the dividend behind the 65 and repeat the process: 652 / 81

Advancing to step 3:
The number 81 fits into 652 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 8.0
If we take 648 away from 652, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 81

Moving on to step 4:
When dividing 42 by 81, we get 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
If we subtract 0 from 42, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 81

Advancing to step 5:
When dividing 422 by 81, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 805.0
If we subtract 405 from 422, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 6:
When dividing 170 by 81, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 805.2
Subtract 162 from 170 to 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.

Let's proceed to step 7:
80 divided by 81 is 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 805.2
Subtracting 0 from 80 leaves us 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:
81 goes into 800 9 times with a remainder of 71.
The number 9 becomes the next digit in our result. 
Result so far: 805.209
Subtracting 729 from 800 leaves us 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.

Going ahead to step 9:
81 can be fit into 710 8 times, resulting in a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 805.2098
If we take 648 away from 710, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
The number 81 fits into 620 7 times, leaving a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 805.20987
Deduct 567 from 620 and we're left with 53.
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:
81 can be fit into 530 6 times, resulting in a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 805.209876
Subtract 486 from 530 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
440 divided by 81 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 805.2098765
The remainder is 35 after subtracting 405 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 13:
350 divided by 81 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 805.20987654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

After the division, we end up with 805.20987654 and a remainder of 2.6e-08.
