The datasheet should give you a logic table for the AND gate.

Most ICs change state when the clock pulses. Instead of trying to see this with a high frequency clock, use a momentary switch to pulse the clock input. You will likely have to install a small capacitor across the switch to prevent false triggering.

4017 is good.
CMOS version of it gives totempole output - which is good.
Check for its speed - will it be fast enough for you?

Drive an AND-gate (ex. 4081) with the output from 4017 and with the output from your 3525.
AND-gate then gives you the PWM signal you need.

Check for their speeds first!
