I am a bit surprised you need a divide by 10 stage, there are many examples on the net of people that are measuring frequencies much higher than 500kHz using the PIO.I use RP2040 as a frequency meter. The program is written on the Arduino Ide.
Maximum measured frequency = 500 kHz. I set the input frequency to pin 0.
To increase the input frequency measurement, I need to make a divider by 10.
