We look at the division of 72428 by 82 
The aim is to understand the frequency of 82 in 72428.

Step 1:
7 divided by 82 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 82

On to step 2:
When dividing 72 by 82, we get 0 with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (4) from the dividend to 72 and continue with: 724 / 82

Step 3:
If we divide 724 by 82, we get 8 and a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 656 from 724 leaves us with 68.
Grab the next digit (2) from the dividend, add it to 68, then carry on: 682 / 82

Let's proceed to step 4:
82 can be fit into 682 8 times, resulting in a remainder of 26.
The number 8 becomes the next digit in our result. 
Result so far: 88.0
The remainder is 26 after subtracting 656 from 682.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 82

On to step 5:
82 goes into 268 3 times with a remainder of 22.
The next digit of our result is 3. 
Result so far: 883.0
The remainder is 22 after subtracting 246 from 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 6:
220 divided by 82 is 2 with a remainder of 56.
Use 2 as the next digit of our solution. 
Result so far: 883.2
If we take 164 away from 220, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 7:
82 goes into 560 6 times with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 883.26
The remainder is 68 after subtracting 492 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
680 divided by 82 is 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 883.268
If we take 656 away from 680, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 9:
When dividing 240 by 82, we get 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 883.2682
Subtract 164 from 240 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 10:
760 divided by 82 is 9 with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 883.26829
If we take 738 away from 760, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 11:
220 divided by 82 is 2 with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 883.268292
Deduct 164 from 220 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
82 can be fit into 560 6 times, resulting in a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 883.2682926
If we subtract 492 from 560, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
When dividing 680 by 82, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 883.26829268
Subtract 656 from 680 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 883.26829268, with a leftover of 2.4e-08.
