We look at the division of 938721 by 82 
The aim is to understand the frequency of 82 in 938721.

Advancing to step 1:
82 goes into 9 0 times with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 82

Moving on to step 2:
82 goes into 93 1 times with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 82 from 93, we get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 82

Moving on to step 3:
If we divide 118 by 82, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 36 after subtracting 82 from 118.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 82

Advancing to step 4:
82 can be fit into 367 4 times, resulting in a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtract 328 from 367 to get 39.
Grab the next digit (2) from the dividend, add it to 39, then carry on: 392 / 82

On to step 5:
82 can be fit into 392 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 1144.0
If we take 328 away from 392, we end up with 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 82

Step 6:
82 can be fit into 641 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 11447.0
Deduct 574 from 641 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
670 divided by 82 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 11447.8
Deduct 656 from 670 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
82 goes into 140 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 11447.81
The remainder is 58 after subtracting 82 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 9:
82 goes into 580 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 11447.817
Subtract 574 from 580 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 10:
82 can be fit into 60 0 times, resulting in a remainder of 60.
The next digit of our result is 0. 
Result so far: 11447.817
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 11:
If we divide 600 by 82, we get 7 and a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 11447.81707
The remainder is 26 after subtracting 574 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 82 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 11447.817073
Subtracting 246 from 260 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 13:
82 can be fit into 140 1 times, resulting in a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 11447.8170731
If we subtract 82 from 140, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 82 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 11447.81707317
The remainder is 6 after subtracting 574 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final outcome is 11447.81707317, with a leftover of 6e-09.
