Let's divide 393213 by 82
The aim is to understand the frequency of 82 in 393213.

On to step 1:
82 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 82

Moving on to step 2:
When dividing 39 by 82, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 82

Advancing to step 3:
82 goes into 393 4 times with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 4.0
If we subtract 328 from 393, we get 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 82

Moving on to step 4:
82 can be fit into 652 7 times, resulting in a remainder of 78.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
The remainder is 78 after subtracting 574 from 652.
Include the next digit (1) from the dividend after 78, then repeat: 781 / 82

Step 5:
When dividing 781 by 82, we get 9 with a remainder of 43.
The next digit of our result is 9. 
Result so far: 479.0
If we take 738 away from 781, we end up with 43.
Bring next digit (3) of the dividend behind the 43 and repeat the process: 433 / 82

On to step 6:
82 can be fit into 433 5 times, resulting in a remainder of 23.
The next digit of our result is 5. 
Result so far: 4795.0
Subtracting 410 from 433 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
82 can be fit into 230 2 times, resulting in a remainder of 66.
The next digit of our result is 2. 
Result so far: 4795.2
If we subtract 164 from 230, we get 66.
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 8:
82 can be fit into 660 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 4795.28
The remainder is 4 after subtracting 656 from 660.
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 9:
82 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4795.28
Deduct 0 from 40 and we're left 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.

On to step 10:
82 can be fit into 400 4 times, resulting in a remainder of 72.
Record the quotient 4 as the next digit in the result. 
Result so far: 4795.2804
If we take 328 away from 400, we end up 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 11:
720 divided by 82 is 8 with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 4795.28048
Subtract 656 from 720 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
If we divide 640 by 82, we get 7 and a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 4795.280487
If we take 574 away from 640, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 13:
The number 82 fits into 660 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 4795.2804878
If we subtract 656 from 660, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
When dividing 40 by 82, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4795.2804878
Deduct 0 from 40 and we're left 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.

Our division results in 4795.2804878 with a remaining 4e-08.
