It really isn't worthwhile to find complicated divisibility rules for large numbers like 305 - because if there really is a divisibility rule, it will certainly be more complicated than just doing the division.
Anyway, 305 = 5 x 61, so if a number is divisible by 305, it must be divisible by 5, and by 61. Divisibility by 5 is fairly simple; a number is divisible by 5 if it ends with 0 or 5. For divisibility by 61, see the following link; it looks fairly complicated.
