Difficulty acquiring good quality mesh

Hello, 
I've encountered quite a lot of difficulty in meshing the below provided part (STEP file).  It's a bearing house, a bearing fits into this part, and then the part is bolted onto the base of our robot. 
I've tried deleting the elements near the holes then using Morphing, projecting nodes onto the hole surface and then filling the gap with pyramid/tetra elements wherever i can, but the final mesh doesn't look right at all as you can see in the picture provided.


Regards,
Vinamra

    You need to divide it into more blocks, morphing is not an approach

    example 

    can you finish it base on this tip?

    Here's my within-5-min mesh:

    Hi Tinh, 
    Thanks for your reply on this, what I am more interested is in the approach you took to mesh it, the main problem with my method was that, due to the mesh flow direction, I had to delete the hole elements, then try to project the surrounding elements near the hole surface onto the hole surface, and it made a mess. So, can you tell me how you approached it? I'm quite new to meshing.
    Sorry for the late reply.
    Thanks again.

    Hello Nguyen,
    Thanks for your prompt reply and the mesh looks quite good, can you rather brief me up with the approach you took towards this model? I'm pretty new in meshing models, this would be really helpful to me.
    Thanks again.

    On my picture, the splitting plans are shown as yellow. So you have already how solid was splitted.
