How can you multiply decimal values without using a multiplication or division operator?

I figured out a problem challenging me to write code to do this with integers, but I was wondering how I would have done it if it had been decimals and I couldn't figure it out.

    Finite representations? Like $.123$ but not $.bar{3}$? Because you can "remove the decimal point" which needn't be exactly the same as multiplication on a programming level and then use whatever system you have to multiply these new integers and then put the decimal point back...
