Let's divide 331054 by 12
We're looking to find how many times 12 goes into 331054.

Step 1:
If we divide 3 by 12, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 12

Step 2:
12 goes into 33 2 times with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 24 from 33 to get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 12

On to step 3:
12 goes into 91 7 times with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Deduct 84 from 91 and we're left with 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 12

Moving on to step 4:
70 divided by 12 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 275.0
If we subtract 60 from 70, we get 10.
Include the next digit (5) from the dividend after 10, then repeat: 105 / 12

Going ahead to step 5:
12 goes into 105 8 times with a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 2758.0
Subtract 96 from 105 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 12

Advancing to step 6:
94 divided by 12 is 7 with a remainder of 10.
The next digit of our result is 7. 
Result so far: 27587.0
Deduct 84 from 94 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 7:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 27587.8
If we subtract 96 from 100, 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.

Let's proceed to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 27587.83
If we take 36 away from 40, we end up 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.

Let's proceed to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 27587.833
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.

Our division results in 27587.833 with a remaining 0.0004.
