ELI5: When exhaling under water there are multiple bubbles, as opposed to 1 singular bubble. Exhaling is a long continuous process without intervals, shouldn't there be 1 long continuous bubble?

Even if it were indeed exhaled in one long continuous process, that doesn't mean the exhaled bubble is structurally stable. It's a long sausage of gas that has to try (unsuccessfully) to hold shape in a moving liquid. That means, basically, that the water pressure causes it to split into smaller, rounder and more stable bubbles.
