If the decimal point is giving you a problem do this

8100

$0.002 = 0.02xx1/10$

$0.002 = 0.2color(white)("d")xx1/10xx1/10$

$0.002=2.0color(white)("d")xx1/10xx1/10xx1/10$

$0.002 = 2xx1/1000$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So $16.2-:0.002color(white)("ddd")$ is the same as

$color(white)("ddd") 16.2-:2-:1/1000$

$color(white)("dddd")8.1-:1/1000$

$color(white)("dddd")8.1xx1000/1 =8100$

$8,100$

The division by the decimal is the biggest problem here.

Luckily we can get rid of the decimal by multiplying by a power of $10$ . We need to multiply it by $1000$

However, we need to multiply the top and bottom by the same number, which is the same as multiplication by $color(blue)(1)$

$16.2/0.002 color(blue)(xx 1000/1000) = 16200/2" "larr$ dividing by a whole number

$16200/2 =8,100$
