Not quite... the dividend yield has nothing to do with it. Check the worksheet and the chart. If you want to take more you can but it would not be required.
At 72 your RMD on an account of $1 million would be 39,062 + 21,250 (85% of 25K) = 60,012
Remember that is just the gross income ... you still get to deduct the standard or itemized deduction + the exemption amount allowed at that time.
