Expected Behavior

A dataset of length 0 should throw an error when initialized instead of throwing a DivisionByZeroError when .start() is invoked

Steps to Reproduce (for bugs)

1. Initialize a ParallelProcessing object with an empty dataset
2. Notice how no error is raised
3. Invoke the .start() method
4. Notice a DivisionByZeroError is raised
