We look at the division of 223956 by 18 
We're looking to find how many times 18 goes into 223956.

Moving on to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 18

Step 2:
When dividing 22 by 18, we get 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we take 18 away from 22, we end up with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 18

Let's proceed to step 3:
The number 18 fits into 43 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 36 from 43 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 18

Moving on to step 4:
If we divide 79 by 18, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 72 from 79 leaves us with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 18

Let's proceed to step 5:
75 divided by 18 is 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 1244.0
If we subtract 72 from 75, we get 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 18

Let's proceed to step 6:
When dividing 36 by 18, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12442.0
If we subtract 36 from 36, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
18 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12442.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
0 divided by 18 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12442.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 12442.0 with a remaining 0.0.
