Three ways I know of:

1 Don't split pelvis, discect around anus from outside until youcan pull the whole thing out with the guts.

2 Split pelvis, discect around anus and pull whole thing out with guts. Same as #1, but it might be easier if you split the pelvis. Pelvis can be split by skillful use of hunting nice, less skilled use of axe or (what I do) with a little hand-held Stanley folding saw. For example:

3.Don't discect around anus. Remove guts as far as possible. Tie two strings tight around intestine as far down the "chute" as you can. Cut intestine between two strings and leave the anus in the deer. The tight strings keep the $hit from leaking around. I've used this method and it's quick and easy.

A friend I have, who's literally cleaned 100s of deer, uses a largish fish fillet knife and cleans a deer in about 3 minutes. He says the fillet knive is nice and thin and allows him to reach in and expertly cut inside the chest and around the anus.
