@biscandmatt yeah really easy, the sections are more 'clean' and come apart easily compared to say hay for pets (which I found would forever conjoin and I'd end up dropping and spelling it all over the place!) I store about three or four sections in my box and that lasts me about 3/4 days but that's feeding two rabbits and 12 piggies! So it should last you much longer! But the whole bale lasts me about 3 weeks or more if I supplement the bun's hay with Timothy.
The other reason I split it is because it is pretty heavy and I couldn't cart it from the shed every day. Oh! And it comes wrapped it a plastic film for travel etc. which if left in can make it sweat so you might need something to store it in if you haven't already
