That is a good question :)

${\frac{{\mathtt{60}}}{{\mathtt{9}}}} = {\frac{{\mathtt{20}}}{{\mathtt{3}}}} = {\mathtt{6.666\: \!666\: \!666\: \!666\: \!666\: \!7}}$

Now

$\\\frac{20}{3}=6\frac{2}{3}\\\\ and\\\\ \frac{2}{3}=0.66666666......\\\\$

the 6's will keep going for ever and ever. If you want to cut them off at some point then the last one should be rounded up to a 7.

This looks like a really good little video clip explaining how numbers are rounded off.
