668921 ÷ 82 
We want to figure out the number of times 668921 can be divided by 82.

Moving on to step 1:
6 divided by 82 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 82

Moving on to step 2:
The number 82 fits into 66 0 times, leaving a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 82

Let's proceed to step 3:
When dividing 668 by 82, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 656 from 668 to get 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 82

Going ahead to step 4:
If we divide 129 by 82, we get 1 and a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 82 away from 129, we end up with 47.
Fetch the next digit (2) from the dividend, attach it to 47 and continue: 472 / 82

Step 5:
If we divide 472 by 82, we get 5 and a remainder of 62.
Write down 5 as next digit of the result. 
Result so far: 815.0
Subtract 410 from 472 to get 62.
Fetch the next digit (1) from the dividend, attach it to 62 and continue: 621 / 82

Advancing to step 6:
The number 82 fits into 621 7 times, leaving a remainder of 47.
The number 7 becomes the next digit in our result. 
Result so far: 8157.0
If we subtract 574 from 621, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 7:
82 can be fit into 470 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 8157.5
If we take 410 away from 470, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
82 can be fit into 600 7 times, resulting in a remainder of 26.
The next digit of our result is 7. 
Result so far: 8157.57
Subtract 574 from 600 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
The number 82 fits into 260 3 times, leaving a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 8157.573
Deduct 246 from 260 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 10:
140 divided by 82 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 8157.5731
The remainder is 58 after subtracting 82 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
If we divide 580 by 82, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 8157.57317
The remainder is 6 after subtracting 574 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
If we divide 60 by 82, we get 0 and a remainder of 60.
The next digit of our result is 0. 
Result so far: 8157.57317
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
82 goes into 600 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 8157.5731707
Subtracting 574 from 600 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 14:
260 divided by 82 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 8157.57317073
The remainder is 14 after subtracting 246 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 8157.57317073 and a remainder of 1.4e-08.
