shuffle
跕 centers on a shuffling, sliding movement of the feet, as when one drags or scuffs along the ground.
跕 combines 足 (foot) with 占, which likely contributes a phonetic element. The exact historical development is uncertain, but the structure suggests a meaning related to foot movement.
The foot radical 足 beside 占 looks like a foot that is stuck or dragging, shuffling along instead of stepping cleanly.
For チョウ, imagine a person shuffling their feet while walking a long, straight corridor: the corridor is a 長 (ちょう) hallway, and the shuffling sound echoes チョウ.
