823622 divided by 21 
Our goal is to divide 823622 by 21.

Moving on to step 1:
21 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 21

Advancing to step 2:
When dividing 82 by 21, we get 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 63 from 82 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 21

On to step 3:
The number 21 fits into 193 9 times, leaving a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 4 after subtracting 189 from 193.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 21

Let's proceed to step 4:
If we divide 46 by 21, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 392.0
If we subtract 42 from 46, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 21

Step 5:
When dividing 42 by 21, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 3922.0
Subtract 42 from 42 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 21

On to step 6:
2 divided by 21 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 39220.0
If we take 0 away from 2, 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.

Let's proceed to step 7:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 39220.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 39220.09
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
When dividing 110 by 21, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 39220.095
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 10:
When dividing 50 by 21, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 39220.0952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
21 goes into 80 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 39220.09523
If we take 63 away from 80, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 12:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 39220.095238
If we take 168 away from 170, 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.

Step 13:
The number 21 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 39220.095238
Subtracting 0 from 20 leaves us with 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 14:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 39220.09523809
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 39220.09523809 with a remainder of 1.1e-08.
