We look at the division of 815286 by 82 
The aim is to understand the frequency of 82 in 815286.

Let's proceed to step 1:
82 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 82

Advancing to step 2:
82 can be fit into 81 0 times, resulting in a remainder of 81.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 81, we end up with 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 82

On to step 3:
When dividing 815 by 82, we get 9 with a remainder of 77.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 738 from 815, we get 77.
Fetch the next digit (2) from the dividend, attach it to 77 and continue: 772 / 82

Let's proceed to step 4:
82 can be fit into 772 9 times, resulting in a remainder of 34.
The next digit of our result is 9. 
Result so far: 99.0
Deduct 738 from 772 and we're left with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 82

Moving on to step 5:
The number 82 fits into 348 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 994.0
Subtract 328 from 348 to get 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 82

Going ahead to step 6:
If we divide 206 by 82, we get 2 and a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9942.0
If we take 164 away from 206, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
82 can be fit into 420 5 times, resulting in a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 9942.5
If we take 410 away from 420, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
82 goes into 100 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 9942.51
Deduct 82 from 100 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
180 divided by 82 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 9942.512
If we subtract 164 from 180, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 10:
When dividing 160 by 82, we get 1 with a remainder of 78.
Put 1 as the next digit of the answer. 
Result so far: 9942.5121
Subtract 82 from 160 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
780 divided by 82 is 9 with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9942.51219
The remainder is 42 after subtracting 738 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
The number 82 fits into 420 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9942.512195
The remainder is 10 after subtracting 410 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
If we divide 100 by 82, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 9942.5121951
Subtracting 82 from 100 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 14:
180 divided by 82 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 9942.51219512
Deduct 164 from 180 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 9942.51219512, and the remainder is 1.6e-08.
