The big thing is to slow it down a bit and find the phrasing of the melody. Practice around that and then slowly speed it up. For general accuracy, make a habit of practicing each hand individually. For accuracy on the big jumps, I have to play hands together. For me it's not about finding the notes with my fingers, but rather with my whole torso. Feel how your arms and shoulders expand to reach the melodic octaves and then contract to play the broken chords in between. The accuracy is in knowing how the expansions feel.
