assuming like most scope inputs, your scope has an input impedance of 1Meg and an input capacitance of 30pf, a resistor in series with the center lead of 100Meg, and a cap parallel to the resistor of 0.3pf should give the required division by 100. voltage dividing scope probes work as a voltage divider with the formula Zp/Zin. since Zin is constant all that needs to be changed is Zp. the capacitance ratio needs to remain the same as the resistor ratio to maintain proper frequency response characteristics. otherwise, square waves begin to look like triangle waves or worse. the compensation cap on a scope probe is usually a variable one so the individual probe can be matched properly with the individual scope input. for a division by 100, i would recommend having the divider at the input connector to minimize errors due to cable capacitance.
appendix A of this app note has all the info you need on scope probes and how they work and why.
