We're dividing 996222 by 21 
Let's see how many times 21 fits into 996222.

Step 1:
If we divide 9 by 21, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 21

On to step 2:
When dividing 99 by 21, we get 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 15 after subtracting 84 from 99.
Fetch the next digit (6) from the dividend, attach it to 15 and continue: 156 / 21

Moving on to step 3:
21 can be fit into 156 7 times, resulting in a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 147 from 156 and we're left with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 21

Advancing to step 4:
If we divide 92 by 21, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 474.0
The remainder is 8 after subtracting 84 from 92.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 21

Advancing to step 5:
21 can be fit into 82 3 times, resulting in a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 4743.0
If we take 63 away from 82, we end up with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 21

Moving on to step 6:
21 goes into 192 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 47439.0
Deduct 189 from 192 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 21, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 47439.1
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 8:
The number 21 fits into 90 4 times, leaving a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 47439.14
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 9:
When dividing 60 by 21, we get 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 47439.142
If we subtract 42 from 60, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
21 can be fit into 180 8 times, resulting in a remainder of 12.
The next digit of our result is 8. 
Result so far: 47439.1428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 21 fits into 120 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 47439.14285
Subtracting 105 from 120 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 12:
If we divide 150 by 21, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 47439.142857
If we take 147 away from 150, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
21 goes into 30 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 47439.1428571
Subtracting 21 from 30 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
90 divided by 21 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 47439.14285714
Subtract 84 from 90 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 47439.14285714 with a remaining 6e-09.
