Very simple solution however I will stress it’s not good engineering practice but It’s often the way garage mechanics get these out (we don’t always do the right thing you might be surprised to learn ;-)).

Okay start by breaking off the split end as much as you can by pulling it backwards and forwards with a needle nose pliers and get as much as you can of the metal pin out.

Now fit your socket short extension and knuckle bar and rock the socket backwards and forwards a couple of times just to shear the split pin loop end.

No fish out as much of the debris of the pin as you can then slowly unwind the nut and remove the hub.

You will obviously need to clean the outer bearing and inner race in the hub to remove any little bits of metal but you will find it almost always is just trapped in the grease.

Clean out the hole drilled in the Stub axle by tapping through a small centre punch, again clean everything up as much as possible.

Finally fit the castellated nut back onto the Stub axle the wrong way round and wind up and down the thread three or four times until you can turn it by hand with no effort, you are simply doing this to clean the threaded area and make sure everything is fine then rebuild as normal when you finished whatever you are doing.

Contradicts all the best engineering practice but when you’re stuck you’re stuck and this is the way mechanics do it in the garage as they don’t faff about trying to get out split pins most would just use an air gun on it and wind it straight off and clean the bearing afterwards as it saves considerable time either side and for mechanics time is money when on bonus!

Remember split pins are very soft metal and never had to drill one as I think that has the potential for disaster if the drill snaps and a small drill bit long enough to get through the stub from outside the splined area???????? Very dodgy.
