668981 ÷ 82 
Our goal is to divide 668981 by 82.

On to step 1:
6 divided by 82 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 82

Step 2:
66 divided by 82 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (8) from the dividend to 66 and continue with: 668 / 82

Step 3:
When dividing 668 by 82, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 656 from 668, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 82

Moving on to step 4:
129 divided by 82 is 1 with a remainder of 47.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
If we take 82 away from 129, we end up with 47.
Append the next digit (8) from the dividend to 47 and continue with: 478 / 82

Moving on to step 5:
82 can be fit into 478 5 times, resulting in a remainder of 68.
Use 5 as the next digit of our solution. 
Result so far: 815.0
Subtract 410 from 478 to get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 82

Step 6:
681 divided by 82 is 8 with a remainder of 25.
Put 8 as the next digit of the answer. 
Result so far: 8158.0
If we subtract 656 from 681, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
82 can be fit into 250 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 8158.3
Deduct 246 from 250 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
The number 82 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8158.3
If we subtract 0 from 40, we get 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 9:
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: 8158.304
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.

On to step 10:
When dividing 720 by 82, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 8158.3048
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.

Advancing to step 11:
640 divided by 82 is 7 with a remainder of 66.
Put 7 as the next digit of the answer. 
Result so far: 8158.30487
Subtracting 574 from 640 leaves us 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.

On to step 12:
If we divide 660 by 82, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8158.304878
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.

On to step 13:
40 divided by 82 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 8158.304878
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 14:
If we divide 400 by 82, we get 4 and a remainder of 72.
The next digit of our result is 4. 
Result so far: 8158.30487804
Deduct 328 from 400 and we're left 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.

Our division results in 8158.30487804 with a remaining 7.2e-08.
