Let's divide 231690 by 82
The aim is to understand the frequency of 82 in 231690.

Advancing to step 1:
2 divided by 82 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 82

Going ahead to step 2:
If we divide 23 by 82, we get 0 and a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 23 and we're left with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 82

Moving on to step 3:
The number 82 fits into 231 2 times, leaving a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 164 from 231 to get 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 82

Going ahead to step 4:
The number 82 fits into 676 8 times, leaving a remainder of 20.
The next digit of our result is 8. 
Result so far: 28.0
The remainder is 20 after subtracting 656 from 676.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 82

On to step 5:
The number 82 fits into 209 2 times, leaving a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
If we subtract 164 from 209, we get 45.
Fetch the next digit (0) from the dividend, attach it to 45 and continue: 450 / 82

Let's proceed to step 6:
82 can be fit into 450 5 times, resulting in a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 2825.0
If we subtract 410 from 450, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
400 divided by 82 is 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 2825.4
Deduct 328 from 400 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 8:
82 goes into 720 8 times with a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 2825.48
Deduct 656 from 720 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 9:
82 goes into 640 7 times with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 2825.487
Subtract 574 from 640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
When dividing 660 by 82, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 2825.4878
Deduct 656 from 660 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
82 goes into 40 0 times with a remainder of 40.
The next digit of our result is 0. 
Result so far: 2825.4878
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 12:
400 divided by 82 is 4 with a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 2825.487804
Subtracting 328 from 400 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
The number 82 fits into 720 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 2825.4878048
If we take 656 away from 720, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 14:
When dividing 640 by 82, we get 7 with a remainder of 66.
The next digit of our result is 7. 
Result so far: 2825.48780487
Subtract 574 from 640 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

In conclusion, the division gives 2825.48780487 with a balance of 6.6e-08.
