We divide 405363 by 12
Our goal is to divide 405363 by 12.

Moving on to step 1:
If we divide 4 by 12, we get 0 and 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.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 12

Advancing to step 2:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 36 from 40, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Step 3:
12 goes into 45 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtract 36 from 45 to get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 12

Step 4:
If we divide 93 by 12, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtracting 84 from 93 leaves us with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 12

Let's proceed to step 5:
96 divided by 12 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 3378.0
If we subtract 96 from 96, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Let's proceed to step 6:
When dividing 3 by 12, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 33780.0
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 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
The next digit of our result is 2. 
Result so far: 33780.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 33780.25
If we take 60 away from 60, 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.

Advancing to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33780.25
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.

Going ahead to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 33780.25
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 33780.25 with a balance of 0.0.
