We're dividing 815143 by 82 
The aim is to understand the frequency of 82 in 815143.

Let's proceed to step 1:
When dividing 8 by 82, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 82

Going ahead to step 2:
81 divided by 82 is 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 82

Moving on to step 3:
82 goes into 815 9 times with a remainder of 77.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 738 from 815, we get 77.
Grab the next digit (1) from the dividend, add it to 77, then carry on: 771 / 82

Moving on to step 4:
771 divided by 82 is 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 738 from 771, we get 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 82

Step 5:
82 goes into 334 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
Subtracting 328 from 334 leaves us with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 82

Step 6:
When dividing 63 by 82, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 9940.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 7:
If we divide 630 by 82, we get 7 and a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 9940.7
Subtracting 574 from 630 leaves us 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.

Let's proceed to step 8:
560 divided by 82 is 6 with a remainder of 68.
Use 6 as the next digit of our solution. 
Result so far: 9940.76
If we take 492 away from 560, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 9:
The number 82 fits into 680 8 times, leaving a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 9940.768
Deduct 656 from 680 and we're left 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.

Moving on to step 10:
240 divided by 82 is 2 with a remainder of 76.
Put 2 as the next digit of the answer. 
Result so far: 9940.7682
The remainder is 76 after subtracting 164 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
82 can be fit into 760 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 9940.76829
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.

Moving on to step 12:
82 can be fit into 220 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 9940.768292
Subtract 164 from 220 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
82 can be fit into 560 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 9940.7682926
Subtracting 492 from 560 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 14:
The number 82 fits into 680 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 9940.76829268
The remainder is 24 after subtracting 656 from 680.
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 9940.76829268, with a leftover of 2.4e-08.
