625905 ÷ 82 
The aim is to understand the frequency of 82 in 625905.

Step 1:
If we divide 6 by 82, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 82

Step 2:
62 divided by 82 is 0 with a remainder of 62.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 82

Going ahead to step 3:
82 can be fit into 625 7 times, resulting in a remainder of 51.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 51 after subtracting 574 from 625.
Take the next digit (9) from the dividend and append it to 51, then repeat: 519 / 82

Advancing to step 4:
When dividing 519 by 82, we get 6 with a remainder of 27.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 27 after subtracting 492 from 519.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 82

Advancing to step 5:
If we divide 270 by 82, we get 3 and a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 763.0
If we take 246 away from 270, we end up with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 82

Let's proceed to step 6:
The number 82 fits into 245 2 times, leaving a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 7632.0
The remainder is 81 after subtracting 164 from 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 7:
The number 82 fits into 810 9 times, leaving a remainder of 72.
The next digit of our result is 9. 
Result so far: 7632.9
If we subtract 738 from 810, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 8:
82 can be fit into 720 8 times, resulting in a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 7632.98
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.

Going ahead to step 9:
82 can be fit into 640 7 times, resulting in a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 7632.987
The remainder is 66 after subtracting 574 from 640.
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:
If we divide 660 by 82, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 7632.9878
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.

Advancing 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: 7632.9878
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 12:
If we divide 400 by 82, we get 4 and a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 7632.987804
The remainder is 72 after subtracting 328 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 82 is 8 with a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 7632.9878048
The remainder is 64 after subtracting 656 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 14:
When dividing 640 by 82, we get 7 with a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 7632.98780487
Subtracting 574 from 640 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final result is 7632.98780487 with a remainder of 6.6e-08.
