We divide 223389 by 12
We're looking to find how many times 12 goes into 223389.

Advancing to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 12

Step 2:
12 goes into 22 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 10 after subtracting 12 from 22.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Advancing to step 3:
The number 12 fits into 103 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtract 96 from 103 to get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 12

Going ahead to step 4:
If we divide 73 by 12, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 186.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

Advancing to step 5:
12 can be fit into 18 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1861.0
Subtracting 12 from 18 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

Step 6:
When dividing 69 by 12, we get 5 with a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 18615.0
The remainder is 9 after subtracting 60 from 69.
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:
12 goes into 90 7 times with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 18615.7
Deduct 84 from 90 and we're left 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.

Moving on to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 18615.75
The remainder is 0 after subtracting 60 from 60.
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 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18615.75
If we subtract 0 from 0, 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 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18615.75
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.

In conclusion, the division gives 18615.75 with a balance of 0.0.
