The word 'apiece' originates from the combination of 'a-' (meaning on or in) and 'piece' (from Old French *piece*, meaning a part or portion). The term 'apiece' refers to each individual part or portion of something.
Think of 'a' meaning 'on' or 'in' and 'piece' meaning 'part' — this helps you remember that 'apiece' refers to each part of something.
