639672 ÷ 82 
The aim is to understand the frequency of 82 in 639672.

Going ahead to step 1:
6 divided by 82 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 82

Going ahead to step 2:
When dividing 63 by 82, we get 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 82

Let's proceed to step 3:
If we divide 639 by 82, we get 7 and a remainder of 65.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 574 from 639 to get 65.
Fetch the next digit (6) from the dividend, attach it to 65 and continue: 656 / 82

Step 4:
The number 82 fits into 656 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 78.0
If we take 656 away from 656, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 82

Step 5:
If we divide 7 by 82, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 780.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 82

Let's proceed to step 6:
82 goes into 72 0 times with a remainder of 72.
The next digit of our result is 0. 
Result so far: 7800.0
Subtract 0 from 72 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.

On to step 7:
82 can be fit into 720 8 times, resulting in a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 7800.8
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.

Moving on to step 8:
If we divide 640 by 82, we get 7 and a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 7800.87
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.

Moving on to step 9:
The number 82 fits into 660 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7800.878
Subtract 656 from 660 to 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.

Let's proceed to step 10:
82 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 7800.878
Subtracting 0 from 40 leaves us 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 11:
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: 7800.87804
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.

Advancing to step 12:
If we divide 720 by 82, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 7800.878048
If we subtract 656 from 720, we 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.

Going ahead to step 13:
82 can be fit into 640 7 times, resulting in a remainder of 66.
The number 7 becomes the next digit in our result. 
Result so far: 7800.8780487
Subtract 574 from 640 to 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.

On to step 14:
660 divided by 82 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 7800.87804878
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.

In conclusion, the division gives 7800.87804878 with a balance of 4e-09.
