822082 ÷ 21 
We're looking to find how many times 21 goes into 822082.

Advancing to step 1:
8 divided by 21 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 21

Let's proceed to step 2:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 19 after subtracting 63 from 82.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 21

On to step 3:
The number 21 fits into 192 9 times, leaving a remainder of 3.
The next digit of our result is 9. 
Result so far: 39.0
Subtract 189 from 192 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 21

Moving on to step 4:
21 can be fit into 30 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 391.0
The remainder is 9 after subtracting 21 from 30.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 21

Going ahead to step 5:
21 goes into 98 4 times with a remainder of 14.
The next digit of our result is 4. 
Result so far: 3914.0
The remainder is 14 after subtracting 84 from 98.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 21

Moving on to step 6:
21 goes into 142 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 39146.0
Subtracting 126 from 142 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
If we divide 160 by 21, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 39146.7
If we take 147 away from 160, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 8:
130 divided by 21 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 39146.76
Subtracting 126 from 130 leaves us 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.

Step 9:
40 divided by 21 is 1 with a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 39146.761
Subtracting 21 from 40 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 10:
21 goes into 190 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 39146.7619
Deduct 189 from 190 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
21 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 39146.7619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
21 goes into 100 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 39146.761904
If we take 84 away from 100, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 39146.7619047
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 14:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 39146.76190476
The remainder is 4 after subtracting 126 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 39146.76190476, with a leftover of 4e-09.
