I suppose it depends on if you’re removing Pleurothallids only. Either way, absolutely soak for a couple minutes. Makes roots more pliable. Pressed cork or tree fern, I’d sorta dig them out of the rest of the material. Then manage the debris off roots.
Using a pair of forceps to wedge under then pry up. Another useful tool in unmounting from cork is the plant label. Slide between roots and cork and twist for the spatula affect or push for that long root.
The grobyi, Socrates is right. Not too much an issue re establishing a division. If you massage it down to the rhizome you can usually find a division point. You might lose a few growths your first time doing this, but grobyi grows fast.
