The adverb is a regular -ly derivation from the adjective 'infinitesimal' with the meaning preserved.

Etymology

Infinitesimally comes from the idea of an 'infinitely small' amount and is related to in- ('not') and finite ('limited'), the same root as infinite. So, to do something infinitesimally is to change it by an almost zero, barely noticeable amount.
