538437 divided by 82 
The aim is to understand the frequency of 82 in 538437.

On to step 1:
When dividing 5 by 82, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 82

On to step 2:
The number 82 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 82

Moving on to step 3:
82 can be fit into 538 6 times, resulting in a remainder of 46.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 492 from 538, we get 46.
Grab the next digit (4) from the dividend, add it to 46, then carry on: 464 / 82

Moving on to step 4:
82 can be fit into 464 5 times, resulting in a remainder of 54.
Write down 5 as next digit of the result. 
Result so far: 65.0
The remainder is 54 after subtracting 410 from 464.
Take the next digit (3) from the dividend and append it to 54, then repeat: 543 / 82

On to step 5:
When dividing 543 by 82, we get 6 with a remainder of 51.
The next digit of our result is 6. 
Result so far: 656.0
Subtract 492 from 543 to get 51.
Grab the next digit (7) from the dividend, add it to 51, then carry on: 517 / 82

On to step 6:
517 divided by 82 is 6 with a remainder of 25.
Write down 6 as next digit of the result. 
Result so far: 6566.0
If we take 492 away from 517, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
82 can be fit into 250 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 6566.3
Subtracting 246 from 250 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
82 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6566.3
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 82 fits into 400 4 times, leaving a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 6566.304
Subtracting 328 from 400 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
If we divide 720 by 82, we get 8 and a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 6566.3048
Subtracting 656 from 720 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 11:
82 can be fit into 640 7 times, resulting in a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 6566.30487
The remainder is 66 after subtracting 574 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
If we divide 660 by 82, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6566.304878
Subtracting 656 from 660 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
When dividing 40 by 82, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 6566.304878
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
If we divide 400 by 82, we get 4 and a remainder of 72.
The number 4 becomes the next digit in our result. 
Result so far: 6566.30487804
Subtract 328 from 400 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 6566.30487804 with a remainder of 7.2e-08.
