I'm no 'expert' in this area but, during research, most of the multipliers I see are doublers and triplers. Anyway, here's an article on their operation.http://jlandrigan.com/files/FREQUENCY%20DOUBLERS%20understanding%20aids%20in%20tube%20operation.pdf
Multivibrators can be used to divide, of course. Here's a generic example. http://www.vias.org/basicradio/basic_radio_31_11.html
More in keeping with the 'analog world' is using an injection locked oscillator to divide. I've got a pdf on it but can't figure out where I got it. Basically, though, an oscillator will tend to 'sync' with another if the signal is large enough and near enough the fundamental or a harmonic so it basically consists of creating a free running osc at (near) the desired frequency and injecting the primary osc signal so the second 'locks' onto it. I was investigating that idea while contemplating an FM stereo multiplexor and the basic circuit can be found at the bottom of this page. http://flipperhome.dyndns.org/FM%20Stereo.htm
The 'divide by two' is on the right side or the schematic.
