I drove for Uber and Lyft (both Ridesharing companies) and used my Van (not my truck) for Real Estate as well. Do I need to divide up all the mileage for each?

Yes, you need to divide the mileage.

The mileage would be applied to each individual Schedule C, so you should be prompted separately for your mileage associated with your real estate business (Industry:  Real Estate & Rental & Leasing), and then again for your rideshare driving (Taxi & limousine service).
