30921 divided by 82 
We're looking to find how many times 82 goes into 30921.

Step 1:
3 divided by 82 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 82

Step 2:
When dividing 30 by 82, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 82

On to step 3:
If we divide 309 by 82, we get 3 and a remainder of 63.
The next digit of our result is 3. 
Result so far: 3.0
If we take 246 away from 309, we end up with 63.
Include the next digit (2) from the dividend after 63, then repeat: 632 / 82

Moving on to step 4:
82 can be fit into 632 7 times, resulting in a remainder of 58.
The next digit of our result is 7. 
Result so far: 37.0
Subtracting 574 from 632 leaves us with 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 82

Let's proceed to step 5:
581 divided by 82 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 377.0
If we subtract 574 from 581, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 6:
70 divided by 82 is 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 377.0
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 7:
The number 82 fits into 700 8 times, leaving a remainder of 44.
The next digit of our result is 8. 
Result so far: 377.08
Subtract 656 from 700 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
440 divided by 82 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 377.085
Subtract 410 from 440 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 9:
82 can be fit into 300 3 times, resulting in a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 377.0853
Subtract 246 from 300 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
82 goes into 540 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 377.08536
Subtracting 492 from 540 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 11:
82 goes into 480 5 times with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 377.085365
Subtracting 410 from 480 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 12:
700 divided by 82 is 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 377.0853658
The remainder is 44 after subtracting 656 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
82 goes into 440 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 377.08536585
Deduct 410 from 440 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 377.08536585, and the remainder is 3e-08.
