Step 1
You can work it out using the usual fraction division process, or just through what is happening
If you take one third and cut it in half ( same as dividing by 2), then each piece will be

\frac{1}{6}

(More pieces, therefore they get smaller)
If you take

\frac{1}{6}

and cut it in half, the pieces get smaller again. Each piece will be

\frac{1}{12}

\frac{1}{3} \div 4 = \frac{1}{3} \div 2 \div 2 = \frac{1}{12}

A nifty short cut: To divide a fraction in half, either halve the top (if it is even) or double the bottom:

\frac{2}{3} \div 2 = \frac{1}{3}

\frac{4}{11} \div 2 = \frac{2}{11}

pretty obvious if you think about it!!

\frac{5}{9} \div 2 = \frac{5}{18}

\frac{7}{8} \div 2 = \frac{7}{16}

In the same way: To divide a fraction by 3 in half, either divide the by 3 (if possible) or treble the bottom:

\frac{6}{11} \div = \frac{2}{11}

share out 6 portions equally.

\frac{5}{8} \div 3 = \frac{5}{24}

Step 1
What you do is the KCF method. Keep, Change, Flip. You would keep the

\frac{1}{3}

. Then you change the divide sign to a multiply sign.
Then you flip the 4 to

\frac{1}{4}

.
You do that since

\frac{1}{4}

is the reciprocal of 4

\frac{1}{3} \div 4 = \frac{1}{3} \times \frac{1}{4}

What is the value of? \frac{1}{3}\div4
