223493 ÷ 18 
Let's see how many times 18 fits into 223493.

Step 1:
18 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 18

Advancing to step 2:
18 can be fit into 22 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 22, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 18

Moving on to step 3:
43 divided by 18 is 2 with 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 (4) of the dividend behind the 7 and repeat the process: 74 / 18

Moving on to step 4:
18 goes into 74 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 124.0
Subtract 72 from 74 to get 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 18

Moving on to step 5:
29 divided by 18 is 1 with a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 1241.0
If we subtract 18 from 29, we get 11.
Bring next digit (3) of the dividend behind the 11 and repeat the process: 113 / 18

Step 6:
The number 18 fits into 113 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 12416.0
Deduct 108 from 113 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.

Going ahead to step 7:
The number 18 fits into 50 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 12416.2
Subtracting 36 from 50 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 12416.27
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
When dividing 140 by 18, we get 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 12416.277
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 12416.277 with a remaining 0.0014.
