We look at the division of 339500 by 12 
Let's see how many times 12 fits into 339500.

Let's proceed to step 1:
3 divided by 12 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 12

Advancing to step 2:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 24 from 33 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 12

Going ahead to step 3:
If we divide 99 by 12, we get 8 and a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 96 away from 99, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 12

Let's proceed to step 4:
The number 12 fits into 35 2 times, leaving a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 282.0
If we subtract 24 from 35, we get 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 12

Step 5:
If we divide 110 by 12, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 2829.0
Subtract 108 from 110 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 12

On to step 6:
If we divide 20 by 12, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 28291.0
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 28291.6
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 28291.66
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 28291.66 and a remainder of 0.008.
