Meaning
第 centers on ordering and sequence: it marks a number in a series (No.) and by extension a graded rank or a place in a sequence. The 'residence' sense is an older, less common application of a place in a series, like a designated dwelling.

Etymology
第 originally combined 竹 (bamboo) with 弟, which likely contributed the sound and the idea of order or sequence, as bamboo strips were tied in order to form early writing tablets. The modern form keeps this structure.
Meaning mnemonic
Picture bamboo strips 竹 tied in order with a string that loops around 丿 and through the inner 弔 shape. The strips are numbered in sequence: 第 marks the order.
Reading mnemonic
For ダイ, imagine a line of bamboo strips forming a giant die (as in dice) that shows the number in the sequence: die -> ダイ, and the die tells you which number it is.
