Answer 1

To express 811 as a repeating decimal, we can divide 811 by 999 (which is one less than 1000, so it will have a repeating decimal pattern of 3 digits).

$$\begin{array}{c|c}
811 & 999 \\
- 799 & \\
\hline
12 & \\
- 9 & \\
\hline
30 & \\
\end{array}$$

We can see that the remainder repeats after the first division, so the decimal representation of 811 is 0.812812812... The cycle of repeating digits is 812.
