Is my work as an accountant in a company that organizes parties where alcohol and dancing are present, with my work confined solely to numbers, considered feeding my children from unlawful earnings?

It is forbidden to work in companies that organize musical concerts and New Year's celebrations where alcoholic beverages are served and dancers are present, even if the work is in accounting, because it constitutes aiding in sin and transgression. However, if you are compelled to this work as a sole opportunity to support your family, then necessities permit prohibitions, with the permissibility ceasing when the necessity ceases.
