We're dividing 223540 by 21 
We want to divide 223540 by 21.

Going ahead to step 1:
2 divided by 21 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 21

Step 2:
22 divided by 21 is 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 22, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 21

On to step 3:
When dividing 13 by 21, we get 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 13 to get 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 21

On to step 4:
When dividing 135 by 21, we get 6 with a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 106.0
Deduct 126 from 135 and we're left with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 21

On to step 5:
21 goes into 94 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 1064.0
If we take 84 away from 94, we end up with 10.
Take the next digit (0) from the dividend and append it to 10, then repeat: 100 / 21

Let's proceed to step 6:
21 goes into 100 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 10644.0
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.

Going ahead to step 7:
160 divided by 21 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 10644.7
The remainder is 13 after subtracting 147 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 8:
21 goes into 130 6 times with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 10644.76
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.

Advancing to step 9:
21 can be fit into 40 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 10644.761
Deduct 21 from 40 and we're left 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.

Advancing 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: 10644.7619
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.

Step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 10644.7619
If we take 0 away from 10, we end up with 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:
The number 21 fits into 100 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10644.761904
Subtracting 84 from 100 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.

Step 13:
21 goes into 160 7 times with a remainder of 13.
The next digit of our result is 7. 
Result so far: 10644.7619047
Subtracting 147 from 160 leaves us 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 14:
When dividing 130 by 21, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 10644.76190476
Deduct 126 from 130 and we're left 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.

The quotient of the division is 10644.76190476, and the remainder is 4e-09.
