344004 divided by 12 
Our goal is to divide 344004 by 12.

Advancing to step 1:
12 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 12

Let's proceed to step 2:
If we divide 34 by 12, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 24 from 34 to get 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 12

Advancing to step 3:
12 goes into 104 8 times with a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 96 from 104 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 12

On to step 4:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
Subtracting 72 from 80 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 12

On to step 5:
If we divide 80 by 12, we get 6 and a remainder of 8.
The next digit of our result is 6. 
Result so far: 2866.0
If we take 72 away from 80, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 12

Going ahead to step 6:
When dividing 84 by 12, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 28667.0
Subtracting 84 from 84 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.

On to step 7:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28667.0
If we subtract 0 from 0, we get 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 8:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28667.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 28667.0 and a remainder of 0.0.
