How many 5 digits can be formed with digits 012345 divisible by 3 with digits not repeated?
0+1+2+3+4+5 = 15 so, if a 5-digit number, formed from these digits, is divisible by 3 it must exclude 0 or 3.
If it excludes 0, all 5*4*3*2*1 = 120 permutations are valid.
If it excludes 3, then 4*4*3*2*1 = 96 permutations are valid (the others start with a zero and so are 4-digit numbers).
That makes a total of 120+96 = 216 numbers.

How do you know if a number is divisible by four?
Whole numbers are divisible by 4 if the number formed by the last two individual digits is evenly divisible by 4. For example, the number formed by the last two digits of the number 2628 is 28, which is evenly divisible by 4 so the number 2628 is evenly divisible by 4.
