To solve the expression $\frac{2.993 \times 10^{10}}{2 \times 10^{-6}}$, we follow these steps:

Step 1: Simplify the numbers

We can rewrite the expression as: $\frac{2.993 \times 10^{10}}{2 \times 10^{-6}} = \frac{2.993}{2} \times \frac{10^{10}}{10^{-6}}$ $\frac{2.993}{2} = 1.4965$

Step 2: Simplify the powers of 10

$\frac{10^{10}}{10^{-6}} = 10^{10 - (-6)} = 10^{16}$

Step 3: Combine the results

$1.4965 \times 10^{16} = 1.4965 \times 10^{16}$

So, the final answer is: $1.4965 \times 10^{16}$
