646043 divided by 82 
The aim is to understand the frequency of 82 in 646043.

Step 1:
If we divide 6 by 82, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 82

Going ahead to step 2:
The number 82 fits into 64 0 times, leaving a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 82

Let's proceed to step 3:
When dividing 646 by 82, we get 7 with a remainder of 72.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 574 from 646 leaves us with 72.
Grab the next digit (0) from the dividend, add it to 72, then carry on: 720 / 82

On to step 4:
When dividing 720 by 82, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 78.0
The remainder is 64 after subtracting 656 from 720.
Append the next digit (4) from the dividend to 64 and continue with: 644 / 82

Let's proceed to step 5:
82 can be fit into 644 7 times, resulting in a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 787.0
Subtract 574 from 644 to get 70.
Append the next digit (3) from the dividend to 70 and continue with: 703 / 82

Going ahead to step 6:
The number 82 fits into 703 8 times, leaving a remainder of 47.
Put 8 as the next digit of the answer. 
Result so far: 7878.0
The remainder is 47 after subtracting 656 from 703.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
470 divided by 82 is 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 7878.5
The remainder is 60 after subtracting 410 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
82 can be fit into 600 7 times, resulting in a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 7878.57
Deduct 574 from 600 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
The number 82 fits into 260 3 times, leaving a remainder of 14.
The next digit of our result is 3. 
Result so far: 7878.573
If we subtract 246 from 260, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 10:
82 goes into 140 1 times with a remainder of 58.
Record the quotient 1 as the next digit in the result. 
Result so far: 7878.5731
Subtract 82 from 140 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
82 can be fit into 580 7 times, resulting in a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 7878.57317
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 12:
When dividing 60 by 82, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 7878.57317
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 13:
If we divide 600 by 82, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 7878.5731707
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.

Moving on to step 14:
82 goes into 260 3 times with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 7878.57317073
The remainder is 14 after subtracting 246 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

In conclusion, the division gives 7878.57317073 with a balance of 1.4e-08.
