We divide 164933 by 81
The aim is to understand the frequency of 81 in 164933.

On to step 1:
The number 81 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 81

Step 2:
The number 81 fits into 16 0 times, leaving a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 81

Let's proceed to step 3:
164 divided by 81 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 162 from 164 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 81

On to step 4:
81 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 29 and we're left with 29.
Bring next digit (3) of the dividend behind the 29 and repeat the process: 293 / 81

Advancing to step 5:
When dividing 293 by 81, we get 3 with a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 203.0
Deduct 243 from 293 and we're left with 50.
Append the next digit (3) from the dividend to 50 and continue with: 503 / 81

Advancing to step 6:
If we divide 503 by 81, we get 6 and a remainder of 17.
The next digit of our result is 6. 
Result so far: 2036.0
Subtract 486 from 503 to 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.

Let's proceed to step 7:
81 goes into 170 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2036.2
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.

Moving on to step 8:
If we divide 80 by 81, we get 0 and a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 2036.2
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
800 divided by 81 is 9 with a remainder of 71.
Use 9 as the next digit of our solution. 
Result so far: 2036.209
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 10:
If we divide 710 by 81, we get 8 and a remainder of 62.
The next digit of our result is 8. 
Result so far: 2036.2098
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.

Let's proceed to step 11:
620 divided by 81 is 7 with a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 2036.20987
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.

Step 12:
530 divided by 81 is 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2036.209876
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 13:
When dividing 440 by 81, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2036.2098765
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 14:
When dividing 350 by 81, we get 4 with a remainder of 26.
Use 4 as the next digit of our solution. 
Result so far: 2036.20987654
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.

In conclusion, the division gives 2036.20987654 with a balance of 2.6e-08.
