I am basically new to programming

Therefore, could any one help me to setup a macro to copy daily Cell
Range K10 to K139 from one Daily Cost file to master Cost file's next
available empty Cell. Example today I copy K10:K139 from Daily cost
file to master cost file C10:C139 and tomorrow it needs to copy to
D10:D139 so on automatically

How do I can write a macro to do the above task.

I will highly appreciate your assistance on this matter.
