散伙 is a separable verb (离合词) meaning a group or relationship breaks up and members go their separate ways. It's used for teams, bands, organizations, or romantic couples. When you need to insert a time word, measure word, or resultative complement, the verb 散 and the noun 伙 split: 散了伙 ('broke up'), 散过两次伙 ('broke up twice'). The object of the breakup is introduced with 和 or 跟, not placed directly after 散伙.
