12 ÷ 3/4:

First, there are many ways to divide a whole number by a fraction. In my way, I take acknowledgment to the rules. There are other ways to do this, like the reciprocal way. To first get started, I'm going to give you the rule which is: (a ÷ b/c = a × c/b). We can now replace our numbers in the variables place.
12 \times  \frac{4}{3}

Second, we can simplify. To do so, (12 × 4 = 48). 48 is our new numerator while we keep the denominator we started out with (3). 
\frac{48}{3}

Third, this is where long division comes in handy. I can't exactly do it on a website, but I am going to try. It is best if done on a piece of paper.

\Mydiv3{%
$\strut#$\kern.25em\smash{\raise.3ex\hbox{$\big)$}}$\mkern-8mu
        \overline{\enspace\strut#48}$} \\ \sf Multiply \ 4 \div \ 3 =1 \ (remainder \ 1) \\ \sf Bring \ down \ 8 \\ \sf 18 \div 3 = 6 \\ \sf 48 \div 3 = 16

 \fbox {16}

2(x+6)-11=6(x/2)+16

This is the equation, when not simplified
