Here is a few circuits: the first is very simple, the second for not too good Xtals (e.g. cheap 32768kHz clock Xtal), the third (i think You need a low freq. pulses) in-built oscillator section of CD4060 binary divider.
What is Your project? The 4017 can work only up to 5MHz. If You relly want to build an oscillator as clock generator, need a couple of divider IC-s from HC serie. The HC 4060 can work up to 24MHz.
