Let us work on the posted problem step by step.

#(2.09 times 10^5) divide (5.006 times 10^{-3})#

by rewriting in fraction form,

#={2.09}/{5.006} times {10^5}/{10^{-3}}#

by computing each factor,

#approx 0.4175 times 10^8#

by rewriting in scientific notation,

#=4.175 times 10^7#

(Caution: The above is not the exact value but an approximation.)


I hope that this was helpful.
