When do you need to write zeros as placeholders when adding or subtracting decimals?

Never think of zeros in a number as place holders (even though they achieve that). A zero is just as much information in a number as a 2, or a 3, or a 5 etc. "215" means two hundreds, one ten and five units. Notice that the 1 here is also a "place holder". "205" means two hundreds, no tens and five units. The zero is just as valid a number as any other, and is treated in ways like any other. You cannot divide by zero, in just the same way that you cannot share 5 apples between no people, but that's an entirely different issue.
