We're dividing 669686 by 82 
The aim is to understand the frequency of 82 in 669686.

Step 1:
82 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 82

On to step 2:
The number 82 fits into 66 0 times, leaving a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (9) from the dividend, add it to 66, then carry on: 669 / 82

On to step 3:
669 divided by 82 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 656 from 669, we get 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 82

Going ahead to step 4:
When dividing 136 by 82, we get 1 with a remainder of 54.
The next digit of our result is 1. 
Result so far: 81.0
The remainder is 54 after subtracting 82 from 136.
Append the next digit (8) from the dividend to 54 and continue with: 548 / 82

Going ahead to step 5:
If we divide 548 by 82, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 816.0
Deduct 492 from 548 and we're left with 56.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 82

On to step 6:
82 goes into 566 6 times with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 8166.0
If we take 492 away from 566, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 7:
When dividing 740 by 82, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 8166.9
Deduct 738 from 740 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
20 divided by 82 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 8166.9
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
When dividing 200 by 82, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 8166.902
The remainder is 36 after subtracting 164 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
82 can be fit into 360 4 times, resulting in a remainder of 32.
The next digit of our result is 4. 
Result so far: 8166.9024
The remainder is 32 after subtracting 328 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
82 can be fit into 320 3 times, resulting in a remainder of 74.
Use 3 as the next digit of our solution. 
Result so far: 8166.90243
Subtracting 246 from 320 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
If we divide 740 by 82, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8166.902439
If we subtract 738 from 740, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 13:
When dividing 20 by 82, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 8166.902439
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 14:
The number 82 fits into 200 2 times, leaving a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 8166.90243902
Subtract 164 from 200 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 8166.90243902 with a balance of 3.6e-08.
