349200 divided by 12 
Let's see how many times 12 fits into 349200.

Advancing to step 1:
12 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

Step 2:
If we divide 34 by 12, we get 2 and a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 24 from 34 to get 10.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 12

Going ahead to step 3:
109 divided by 12 is 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 108 from 109, we get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 12

On to step 4:
When dividing 12 by 12, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 291.0
Subtracting 12 from 12 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 12

Going ahead to step 5:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2910.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Going ahead to step 6:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29100.0
Subtracting 0 from 0 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.

Advancing to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 29100.0
Subtract 0 from 0 to 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.
Record the quotient 0 as the next digit in the result. 
Result so far: 29100.0
Subtracting 0 from 0 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.

After the division, we end up with 29100.0 and a remainder of 0.0.
