Yes, you can divide the tablet in 4 pieces.

Metoprolol succinate ER is one of the few extended release medications that doesn't lose efficacy when cut in half because of its micro capsule formulation. However it loses efficacy if you do cut it into quarters. 6.25 mgs is such a tiny dose but it may.provide some tapering effect for you,however.
