42363 ÷ 12 
Let's see how many times 12 fits into 42363.

On to step 1:
12 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

On to step 2:
When dividing 42 by 12, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 36 from 42 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 12

Let's proceed to step 3:
12 can be fit into 63 5 times, resulting in a remainder of 3.
The next digit of our result is 5. 
Result so far: 35.0
If we take 60 away from 63, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 12

Moving on to step 4:
12 goes into 36 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 353.0
Subtracting 36 from 36 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 12

Moving on to step 5:
12 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 3530.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 6:
The number 12 fits into 30 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 3530.2
Subtract 24 from 30 to get 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 7:
If we divide 60 by 12, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 3530.25
Subtracting 60 from 60 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.

Advancing to step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3530.25
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.

Moving on to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3530.25
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.

In conclusion, the division gives 3530.25 with a balance of 0.0.
