The kanji 番 is a pictophonetic character. The left part is 釆, which originally depicted a footprint, indicating tracking. The right part is 田, meaning field. The original meaning might have been related to following footprints in a field to track something. Later, it evolved to represent a series of footprints or marks, thus representing an "order" or "sequence." The character then adopted its current form to become 番.
