Okay, that ending = will create confusion.
So let's break it.
Base 64 creates groups where each group has 3 BYTES (each byte equals 1 character) but Hello has only 5 Characters so we add 1 byte (8 Zeros) at the end.
Now we break bytes into 6 bits and we are left with
This 6 Zero corresponds to A of base 64, but since these zeros were our padding and not the real data so that 6 Zeros is considered =.

I always wondered about that, just had never taken the time to look it up. But your explanation is probably way better than anything else out there.
