| The plant is commonly called 'Dancing Lady' there are several varieties sold throughout Florida including Taka, Grower Ramsey, and Sweet Sugar among others.
I can ID it from the photo since there are quite a few this big in Florida and it is such a common hybrid. Many Oncidium can get this big but the other types are not as common. Only an inexpensive orchid would have been ignored long enough to get this big. Pampered orchids never do as well.
As to its size, I have a friend that has one twice this size. Hers is almost 8 feet across. I did not believe it was an orchid the first time I saw it. they are a commercial landscape nursery and I though it was a hedge.
As to taking a division, do not worry. This is such a strong plant there is almost nothing you can do it hurt the parent plant. Get a piece along the outside. Take three or four bulbs (a fist full is about right) and twist it off. Put a little cinnamon for fungus protection on the piece and re-pot.
Be careful on watering the division. It has always been in air without a pot and will take some adaptation to growing in a pot.
It would do well in a basket with large bark. This is one of the few times I recommend large bark, but you would not really be potting the cutting but growing it bare root with the bark there to retain water and moisture around the roots. You could hang the basket or place it on a table until it takes over the table like your friends.
