View High Voltage AC Signal on Oscilloscope
The main problem of your divider is that it consumes pretty high current. 

In general, the oscilloscope (or any other voltmeter type device) needs to has as higher input impedance as possible. 

As a rule the input impedance should be 10MOhm and even higher. 

Although, the high resistance needs some frequency compensation in order to divide all frequencies by the same coefficient.

If your signal source is powerful enough and can handle such low impedance without affecting the signal properties, then no problem to use your divider.

Anyway, using voltage dividing probe (10x) that contains high impedance, frequency compensated divider, can save you a lot of troubles and to increase the accuracy of your measurements.
