Let's divide 282106 by 81
The aim is to understand the frequency of 81 in 282106.

On to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 81

Advancing to step 2:
When dividing 28 by 81, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 81

Advancing to step 3:
If we divide 282 by 81, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 39 after subtracting 243 from 282.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 81

Advancing to step 4:
The number 81 fits into 391 4 times, leaving a remainder of 67.
The number 4 becomes the next digit in our result. 
Result so far: 34.0
Subtract 324 from 391 to get 67.
Take the next digit (0) from the dividend and append it to 67, then repeat: 670 / 81

Step 5:
If we divide 670 by 81, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 348.0
Deduct 648 from 670 and we're left with 22.
Grab the next digit (6) from the dividend, add it to 22, then carry on: 226 / 81

Advancing to step 6:
The number 81 fits into 226 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 3482.0
If we subtract 162 from 226, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 7:
640 divided by 81 is 7 with a remainder of 73.
Write down 7 as next digit of the result. 
Result so far: 3482.7
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 8:
When dividing 730 by 81, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 3482.79
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
If we divide 10 by 81, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 3482.79
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
81 can be fit into 100 1 times, resulting in a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 3482.7901
Subtract 81 from 100 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 11:
The number 81 fits into 190 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 3482.79012
If we subtract 162 from 190, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 12:
The number 81 fits into 280 3 times, leaving a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3482.790123
If we subtract 243 from 280, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 13:
If we divide 370 by 81, we get 4 and a remainder of 46.
The next digit of our result is 4. 
Result so far: 3482.7901234
The remainder is 46 after subtracting 324 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 14:
81 can be fit into 460 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 3482.79012345
If we take 405 away from 460, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final result is 3482.79012345 with a remainder of 5.5e-08.
