'totaling' originates from English, formed from the verb 'total' plus the suffix '-ing,' where '-ing' forms the present participle/gerund.

'total' came from Middle French word 'total,' from Medieval Latin 'totalis,' from Latin 'totus' meaning 'all, whole'; adding English suffix '-ing' produced the modern form 'totaling.'

Initially, 'total' meant 'entire/whole'; as a verb it developed the sense 'to add up to a sum,' and with '-ing' it came to denote the ongoing action or the act of summing.
