331459 ÷ 12 
Our goal is to divide 331459 by 12.

Step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Let's proceed to step 2:
12 goes into 33 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 24 from 33 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 12

Step 3:
When dividing 91 by 12, we get 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 84 away from 91, we end up with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

Step 4:
12 can be fit into 74 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 276.0
Subtracting 72 from 74 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 12

Let's proceed to step 5:
The number 12 fits into 25 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2762.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 12

Let's proceed to step 6:
If we divide 19 by 12, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 27621.0
Subtracting 12 from 19 leaves us with 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:
When dividing 70 by 12, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 27621.5
Deduct 60 from 70 and we're left 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.

Step 8:
12 can be fit into 100 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 27621.58
Deduct 96 from 100 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.

On to step 9:
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: 27621.583
If we subtract 36 from 40, we 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 10:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 27621.5833
Subtracting 36 from 40 leaves us 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.

The final result is 27621.5833 with a remainder of 4e-05.
