We look at the division of 12243 by 4 
Our goal is to divide 12243 by 4.

Step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 4

Advancing to step 2:
4 goes into 12 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 12 from 12, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 4

On to step 3:
4 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 30.0
If we take 0 away from 2, we end up with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Step 4:
When dividing 24 by 4, we get 6 with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 306.0
If we subtract 24 from 24, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Let's proceed to step 5:
If we divide 3 by 4, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 3060.0
Subtracting 0 from 3 leaves us 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 6:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 3060.7
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 7:
If we divide 20 by 4, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3060.75
Deduct 20 from 20 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.

Advancing to step 8:
4 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3060.75
Subtracting 0 from 0 leaves us 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.

Moving on to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3060.75
The remainder is 0 after subtracting 0 from 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 3060.75 with a balance of 0.0.
