to remove
取 — ear 耳 + hand 又
取 originally depicted a hand (又) grasping an ear (耳), referencing the ancient practice of soldiers cutting off enemies' left ears as proof of kills to claim rewards. The meaning broadened from 'seize/take by force' to the general sense of 'take, get, obtain' used today.
除 — left ear/mound 阝 + surplus 余
除 combines the 'mound/steps' radical 阝 (originally 阜, a hill) with 余 as the phonetic. It first meant the steps of a palace, then extended to 'remove' or 'clear away' (as one sweeps steps clean), and later to mathematical 'divide.'
