We divide 21684 by 82
Let's see how many times 82 fits into 21684.

Step 1:
2 divided by 82 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 82

Advancing to step 2:
The number 82 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 82

Step 3:
82 goes into 216 2 times with a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 164 from 216 leaves us with 52.
Append the next digit (8) from the dividend to 52 and continue with: 528 / 82

Moving on to step 4:
82 can be fit into 528 6 times, resulting in a remainder of 36.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Deduct 492 from 528 and we're left with 36.
Take the next digit (4) from the dividend and append it to 36, then repeat: 364 / 82

Moving on to step 5:
The number 82 fits into 364 4 times, leaving a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 264.0
Deduct 328 from 364 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 6:
The number 82 fits into 360 4 times, leaving a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 264.4
If we take 328 away from 360, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
82 can be fit into 320 3 times, resulting in a remainder of 74.
Record the quotient 3 as the next digit in the result. 
Result so far: 264.43
If we take 246 away from 320, 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.

Let's proceed to step 8:
82 can be fit into 740 9 times, resulting in a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 264.439
If we take 738 away from 740, we end up 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.

Advancing to step 9:
When dividing 20 by 82, we get 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 264.439
If we subtract 0 from 20, we 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.

Going ahead to step 10:
82 goes into 200 2 times with a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 264.43902
If we subtract 164 from 200, we 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.

Step 11:
If we divide 360 by 82, we get 4 and a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 264.439024
Subtract 328 from 360 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 12:
The number 82 fits into 320 3 times, leaving a remainder of 74.
The number 3 becomes the next digit in our result. 
Result so far: 264.4390243
Deduct 246 from 320 and we're left 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.

Advancing to step 13:
82 goes into 740 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 264.43902439
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.

The final result is 264.43902439 with a remainder of 2e-09.
