4.002.
The steps for this are as follows:
Set up the equation, 24.012 divided by 6.
Six cannot go into 2, so the first number is going to be zero. Drop down the 4 to make the number 24, and divide by 4. This makes the second number 4.
Next you have to make sure you place the decimal up to the final answer and bring down the zero. Since six can’t be divided into zero, the next number above is 0. Bring down the one, again can’t be divided so put a zero. Then bring down the two to make the number twelve and bring up the two.
