Very big Monstera plant (Gorse Hill M32)

This was given to me recently, but once I saw how big it was I realised it was far too big for the space in my room.
It is currently on my patio, I was going to try and cut it down a bit and take cuttings, but I have no idea where to start as its so big.
First picture is the one that was sent to me and why I took it, but the 2nd and 3rd pictures were taken today so make sure you look at those to get an idea of the true size before asking for it.
It is currently in a big planter inside a bin bag so the soil wouldn't escape when it was transported and there is a saucer to go with it.
Would like it to go asap as if the weather changes I don't know how it will cope outside and I don't want to have to take to the tip.
