division of labor (splitting duties with partner)

If one parent travels for work (overnight, 3-4 days a week) and the other parent does not travel and instead works a "normal" 9-5, how should household labor be divided? I am thinking of day to day housework with kids, like making dinner, driving kids to activities, laundry, daily kitchen...

We have three kids together. They do: All baby feedings (1.5 year old) Homework supervision (7 year old) Clothes Acquisition/decisions Interface with school Clean floors Clean litterboxes Their own laundry Summer 9-5 Watch kids (they are a college professor, I work year round)...
