Looks like you have a valid pulse going to the input of the divider (pin1). I would suspect that power supply noise might be causing problems. Do you have any capacitors at your disposal? Something in the range of 10uF to 100 uF? If so, try installing it between pin 7 and pin 14 (Vdd & Gnd) of the IC ..... remember to observe the polarity of the capacitor.
If you do not have a capacitor, then I would suggest using three 1.5V batteries in series as your power source.
