687771 divided by 82 
The aim is to understand the frequency of 82 in 687771.

Advancing 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
Subtract 0 from 6 to get 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 82

Moving on to step 2:
82 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (7) of the dividend behind the 68 and repeat the process: 687 / 82

Step 3:
If we divide 687 by 82, we get 8 and a remainder of 31.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Deduct 656 from 687 and we're left with 31.
Append the next digit (7) from the dividend to 31 and continue with: 317 / 82

Going ahead to step 4:
317 divided by 82 is 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 83.0
Subtracting 246 from 317 leaves us with 71.
Fetch the next digit (7) from the dividend, attach it to 71 and continue: 717 / 82

Going ahead to step 5:
717 divided by 82 is 8 with a remainder of 61.
Use 8 as the next digit of our solution. 
Result so far: 838.0
Subtracting 656 from 717 leaves us with 61.
Append the next digit (1) from the dividend to 61 and continue with: 611 / 82

Advancing to step 6:
82 can be fit into 611 7 times, resulting in a remainder of 37.
Write down 7 as next digit of the result. 
Result so far: 8387.0
Subtract 574 from 611 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
82 goes into 370 4 times with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 8387.4
Subtract 328 from 370 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
The number 82 fits into 420 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8387.45
If we subtract 410 from 420, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 9:
82 can be fit into 100 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 8387.451
The remainder is 18 after subtracting 82 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 10:
180 divided by 82 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 8387.4512
Subtracting 164 from 180 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
160 divided by 82 is 1 with a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 8387.45121
Subtracting 82 from 160 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 12:
The number 82 fits into 780 9 times, leaving a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 8387.451219
If we subtract 738 from 780, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 13:
420 divided by 82 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8387.4512195
If we subtract 410 from 420, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 82 fits into 100 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 8387.45121951
If we subtract 82 from 100, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 8387.45121951 and a remainder of 1.8e-08.
