64 bit multiplication / splitting register

[mnkyskilz]

hello, i am writing a mips assembly program where i must multiply two 64 bit unsigned integers. I understand that i must first take one integer divide it into hi lo and do the same with the second and multiply these four parts. My question is when i read an integer from the console how can i split this integer into two registers of 32 bits each so i can then multply the 4 registers together. if anyone has any code or something similar to this it would be greatly appreciated.Thank you
