Ouch.
That sounds more like a software solution than a hardware one
But vhdl can cope .
You need to first use vhdl 2008 or later , with the floating point package .
Then , convert the two 64 bit numbers to float , and do a float divide.
What format are the two 64 bit numbers ? 2s compliment ? Unsigned binary ?

It is unsigned.
how I can set floating point package?

floating point is part of vhdl 2008

but why do yo need floating point ?
