`5/6= 0.833bar3`

`color(white)("X")underline(color(white)("0").color(white)("0")8color(white)("0")3color(white)("0")3color(white)("0")bar(3) ...)`
`6 ) 5 .color(white)("0")0color(white)("0")0color(white)("0")0color(white)("0")0color(white)("0")...`
`color(white)("X")underline(4 .color(white)("0")8)`
`color(white)("XXX")2color(white)("0")0`
`color(white)("XXX")underline(1color(white)("0")8)`
`color(white)("XXXxX")2color(white)("0")0`
`color(white)("XXXxX")underline (1color(white)("0")8)`
`color(white)("XXXXXX")2 ...`

The "bar" over the `3` indicates that this digit is repeated infinitely.

Answer 2

I got: `0.8bar3`

Explanation:

We can try performing the division:
`5:6=`

where we took a zero to get `50` and be able to perform the division introducing the decimal `0.`
