Took me like 45 Minutes maybe less but this is only a bust. I learn this from several videos on the web there are good videos in youtube that show the complete proccess. You can also use ZRemesher but it doesn't give you the control over topology like Zspheres, It is a good way to get Topo fast and continue sculpting since it gives you good result in no time. But again if you want more control on were to place your vertices use zspheres. All you need is patience , also there is topogon if you dont want to use zbrush for topology and it is waaaayy simpler to do it in there.
So look for Zremesher, Zsphere Retopology, Topogun and if you want to do it in Maya you can import a decimated version of your ZB Model, Make it Live then use the append to polygon tool or the new tool kit.
Anyways Hope this helps.Take care.
