We look at the division of 639896 by 82 
The aim is to understand the frequency of 82 in 639896.

Step 1:
82 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 82

Let's proceed to step 2:
82 goes into 63 0 times with a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 82

Let's proceed to step 3:
639 divided by 82 is 7 with a remainder of 65.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 574 from 639 and we're left with 65.
Bring next digit (8) of the dividend behind the 65 and repeat the process: 658 / 82

Advancing to step 4:
82 goes into 658 8 times with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Deduct 656 from 658 and we're left with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 82

Step 5:
When dividing 29 by 82, we get 0 with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 780.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (6) from the dividend, attach it to 29 and continue: 296 / 82

Step 6:
If we divide 296 by 82, we get 3 and a remainder of 50.
Put 3 as the next digit of the answer. 
Result so far: 7803.0
If we take 246 away from 296, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 7:
When dividing 500 by 82, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 7803.6
Subtracting 492 from 500 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
The number 82 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 7803.6
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 9:
If we divide 800 by 82, we get 9 and a remainder of 62.
The next digit of our result is 9. 
Result so far: 7803.609
If we take 738 away from 800, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 10:
620 divided by 82 is 7 with a remainder of 46.
Use 7 as the next digit of our solution. 
Result so far: 7803.6097
Subtract 574 from 620 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 11:
82 can be fit into 460 5 times, resulting in a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 7803.60975
If we take 410 away from 460, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 82, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 7803.609756
Subtract 492 from 500 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
When dividing 80 by 82, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 7803.609756
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 14:
The number 82 fits into 800 9 times, leaving a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 7803.60975609
If we take 738 away from 800, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 7803.60975609 with a balance of 6.2e-08.
