Can a Beast Master ranger break up his turn between actions his beast does?

@JeremyECrawford can a BM ranger break up his turn between actions his beast does? Or are they two separate turns on the same initiative?

The Beast Master ranger and the beast have separate turns on the same initiative count. #DnD https://t.co/QHcV5Zc4pL
