You can enter in multiple spouses in the Edit mode. Click the EDIT tab from across the top, scroll down the right side, click (add/remove) spouse, then add the next spouse.
Often when this is the case, you would enter the marriage end date for one marriage, and then that delineates the time frame., the same way marriage end date is added when a spouse dies, and another marriage occurs.
If you don't have an actual divorce date, you can enter an approximate - ie. about/uncertain year, prior to the next marriage date.
