$7.311 \times {10}^{5}$

#### Explanation:

$\textcolor{w h i t e}{. .} 7.4 \times {10}^{5}$
$\textcolor{w h i t e}{.} 74.0 \times {10}^{4}$
$740.0 \times {10}^{3} \leftarrow \text{ we can now do the subtraction as same } {10}^{n}$

$740.0 \times {10}^{3}$
$\underline{\textcolor{w h i t e}{74} 8.9 \times {10}^{3}} \leftarrow \text{ subtract}$
$731.1 \times {10}^{3}$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
$731.100 \times {10}^{3}$
$\textcolor{w h i t e}{3} 73.110 \times {10}^{4}$
$\textcolor{w h i t e}{77} 7.311 \times {10}^{5}$

$\text{ } \textcolor{g r e e n}{\overline{\underline{| \textcolor{w h i t e}{\frac{2}{2}} 7.311 \times {10}^{5} \textcolor{w h i t e}{2} |}}}$
