$\cdot 33715E01$

$0.8642E02÷0.2562E02=?$
The Scientific format displays a number in exponential notation, replacing part of the number with $E+n$, where $E$ (stands for exponent) multiplies the preceding number by $10$ to the $n^{th}$ power.
That is $1.23E+10$ can be written as $1.23\times {10}^{10}$
$0.8642E02÷0.2562E02=\frac{0.8642\times {10}^2}{0.2562\times {10}^2}$
$=\frac{0.8642}{0.2562}$
$=3.371459$
$=0.3371459\times {10}^1$
$=0.33715E01$
$0.8642E02÷0.2562E02=0.33715E01$
