Pretty much the way that auchencrow and Salubrious describe the process is the way I try to approach installing new cotters. The only other thing I might add is that if you have the cotters that came out of the arms, they can, though not always, be useful for making a comparison on the replacement cotters. As already mentioned, it's better to be conservative and not take too much material off the cotter.

BTW, where do you get the idea that need to have your cranks 180° apart?

I would venture to say there are plenty of folks with cottered cranks that are a couple degrees apart and don't even notice it. I'm probably even one of those people.
