For example..without a calculator is there any easy way to find the value of [itex]\frac{1}{19}[/itex] or any fraction in which the denominator ends in a '9' ?

Not that I know of. If the denominator is a divisor of a number of the form 99...900..0 then there is an easy way. For example:
7/33 = 21/99 = 0.21212121...
2/55 = 36/990 = 0.036363636...
8/3700 = 216/99900 = 0.00216216216...

To find the decimal representation of a fraction, I find long division to be pretty fast and easy...
