We look at the division of 657741 by 82 
The aim is to understand the frequency of 82 in 657741.

On to step 1:
The number 82 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 82

Step 2:
82 goes into 65 0 times with a remainder of 65.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Bring next digit (7) of the dividend behind the 65 and repeat the process: 657 / 82

Step 3:
When dividing 657 by 82, we get 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 656 from 657 leaves us with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 82

Advancing to step 4:
If we divide 17 by 82, we get 0 and a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 82

Going ahead to step 5:
The number 82 fits into 174 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 802.0
The remainder is 10 after subtracting 164 from 174.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 82

On to step 6:
101 divided by 82 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 8021.0
The remainder is 19 after subtracting 82 from 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
82 can be fit into 190 2 times, resulting in a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 8021.2
Subtract 164 from 190 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
When dividing 260 by 82, we get 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 8021.23
Subtracting 246 from 260 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
82 goes into 140 1 times with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 8021.231
Deduct 82 from 140 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

On to step 10:
82 can be fit into 580 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 8021.2317
Subtracting 574 from 580 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
82 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8021.2317
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
82 goes into 600 7 times with a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 8021.231707
The remainder is 26 after subtracting 574 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
If we divide 260 by 82, we get 3 and a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 8021.2317073
Subtracting 246 from 260 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 14:
82 can be fit into 140 1 times, resulting in a remainder of 58.
Write down 1 as next digit of the result. 
Result so far: 8021.23170731
Subtracting 82 from 140 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 8021.23170731 with a remaining 5.8e-08.
