223911 divided by 21 
We want to divide 223911 by 21.

Going ahead to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 21

Let's proceed to step 2:
21 can be fit into 22 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 21 from 22 and we're left with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 21

Going ahead to step 3:
The number 21 fits into 13 0 times, leaving a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 13, we get 13.
Fetch the next digit (9) from the dividend, attach it to 13 and continue: 139 / 21

Going ahead to step 4:
The number 21 fits into 139 6 times, leaving a remainder of 13.
The number 6 becomes the next digit in our result. 
Result so far: 106.0
If we subtract 126 from 139, we get 13.
Fetch the next digit (1) from the dividend, attach it to 13 and continue: 131 / 21

Moving on to step 5:
21 goes into 131 6 times with a remainder of 5.
Record the quotient 6 as the next digit in the result. 
Result so far: 1066.0
If we subtract 126 from 131, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 21

Step 6:
21 can be fit into 51 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 10662.0
Subtracting 42 from 51 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.

Moving on to step 7:
90 divided by 21 is 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 10662.4
Subtracting 84 from 90 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
21 goes into 60 2 times with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 10662.42
Subtracting 42 from 60 leaves us with 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 9:
When dividing 180 by 21, we get 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 10662.428
Deduct 168 from 180 and we're left 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.

Step 10:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 10662.4285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 10662.42857
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.

On to step 12:
If we divide 30 by 21, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 10662.428571
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.

On to step 13:
21 can be fit into 90 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 10662.4285714
If we take 84 away from 90, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
60 divided by 21 is 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 10662.42857142
Subtracting 42 from 60 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 10662.42857142, and the remainder is 1.8e-08.
