$994.14-:18.9=52.6$

$994.14-:18.9=99414/100-:189/10$

As dividing by a number is equivalent to multiplying by its multiplicative inverse

$994.14-:18.9=99414/100xx10/189$ .

Now divisibility rule of $9$ indicates that $99414$ and $189$ , both are divisible by $9$ , hence

$994.14-:18.9=(11046cancel(99414)xxcancel(10))/(10cancel(100)xx21cancel(189))=11046/(10xx21)$

Now $11046$ and $21$ are divisible by $3$ and $7$ , hence

$994.14-:18.9=(526cancel(3682)cancel(11046))/(10xx1cancel7cancel(21))=52.6$
