We look at the division of 55866 by 82 
The aim is to understand the frequency of 82 in 55866.

On to step 1:
When dividing 5 by 82, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 82

Step 2:
55 divided by 82 is 0 with a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Append the next digit (8) from the dividend to 55 and continue with: 558 / 82

Advancing to step 3:
If we divide 558 by 82, we get 6 and a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 492 from 558 and we're left with 66.
Grab the next digit (6) from the dividend, add it to 66, then carry on: 666 / 82

Step 4:
The number 82 fits into 666 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we subtract 656 from 666, we get 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 82

Step 5:
The number 82 fits into 106 1 times, leaving a remainder of 24.
Put 1 as the next digit of the answer. 
Result so far: 681.0
Subtracting 82 from 106 leaves us 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.

Let's proceed to step 6:
240 divided by 82 is 2 with a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 681.2
Deduct 164 from 240 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 7:
The number 82 fits into 760 9 times, leaving a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 681.29
Deduct 738 from 760 and we're left 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.

Step 8:
220 divided by 82 is 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 681.292
Subtracting 164 from 220 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 9:
The number 82 fits into 560 6 times, leaving a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 681.2926
Subtract 492 from 560 to 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.

Moving on to step 10:
680 divided by 82 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 681.29268
If we subtract 656 from 680, we 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.

On to step 11:
82 can be fit into 240 2 times, resulting in a remainder of 76.
The next digit of our result is 2. 
Result so far: 681.292682
Deduct 164 from 240 and we're left with 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 12:
760 divided by 82 is 9 with a remainder of 22.
The next digit of our result is 9. 
Result so far: 681.2926829
The remainder is 22 after subtracting 738 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
The number 82 fits into 220 2 times, leaving a remainder of 56.
Write down 2 as next digit of the result. 
Result so far: 681.29268292
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.

The final result is 681.29268292 with a remainder of 5.6e-08.
