405283 divided by 12 
We want to divide 405283 by 12.

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
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 12

Going ahead to step 2:
40 divided by 12 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 36 from 40 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 12

Let's proceed to step 3:
12 goes into 45 3 times with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 36 from 45 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 12

Step 4:
12 goes into 92 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 337.0
Subtract 84 from 92 to get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 12

Let's proceed to step 5:
If we divide 88 by 12, we get 7 and a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 3377.0
Subtracting 84 from 88 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 12

On to step 6:
If we divide 43 by 12, we get 3 and a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 33773.0
If we subtract 36 from 43, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 33773.5
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 33773.58
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 33773.583
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
12 goes into 40 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 33773.5833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 33773.5833 with a balance of 4e-05.
