We're dividing 500488 by 81 
The aim is to understand the frequency of 81 in 500488.

Let's proceed to step 1:
5 divided by 81 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 81

Going ahead to step 2:
50 divided by 81 is 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Fetch the next digit (0) from the dividend, attach it to 50 and continue: 500 / 81

Step 3:
500 divided by 81 is 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 486 from 500 and we're left with 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 81

Advancing to step 4:
When dividing 144 by 81, we get 1 with a remainder of 63.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 81 from 144 leaves us with 63.
Take the next digit (8) from the dividend and append it to 63, then repeat: 638 / 81

Moving on to step 5:
The number 81 fits into 638 7 times, leaving a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 617.0
Subtract 567 from 638 to get 71.
Append the next digit (8) from the dividend to 71 and continue with: 718 / 81

Let's proceed to step 6:
81 goes into 718 8 times with a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 6178.0
Subtract 648 from 718 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
81 can be fit into 700 8 times, resulting in a remainder of 52.
The next digit of our result is 8. 
Result so far: 6178.8
If we subtract 648 from 700, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
When dividing 520 by 81, we get 6 with a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 6178.86
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 9:
When dividing 340 by 81, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6178.864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 81 is 1 with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 6178.8641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 11:
81 can be fit into 790 9 times, resulting in a remainder of 61.
The next digit of our result is 9. 
Result so far: 6178.86419
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Going ahead to step 12:
81 goes into 610 7 times with a remainder of 43.
The next digit of our result is 7. 
Result so far: 6178.864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 13:
The number 81 fits into 430 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6178.8641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 14:
If we divide 250 by 81, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 6178.86419753
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final outcome is 6178.86419753, with a leftover of 7e-09.
