Your result should fit the form, U.Tx10^p, where U is the digit in the ones place, T is the digit in the tenths place, and p is the exponent, an integer. The "x" is used only as a multiplication symbol.

2.9X10^7 / 5.8X10^10
You mean
%282.9x10%5E7%29%2F%285.8x10%5E10%29
=%282.9%2F5.8%29x10%5E%287-10%29
=0.5x10%5E%28-3%29=5.0x10%5E%28-1%29x10%5E%28-3%29=highlight%285.0x10%5E%28-4%29%29

The system is not rendering everything properly. The highlighted number should show 5.0 x 10^(-4), because we should keep two significant figures for the available accuracy, according to the accuracy available for the starting numbers.
