Why do I get $\mathrm{0.098765432098765432...}$ when I divide 8 by 81?

I got this remarkable thing when I divided 16 by 162, or, in a simplified version, 8 by 81. It's $0.098765432098765432\cdots $ , or more commonly known as $0.\overline{098765432}$ with all the one-digit numbers going backwards...except for 1. Yeah, it's missing the 1. One, how do I get this remarkable outcome and two, why is it missing the 1?
