Imagine you're trying to divide 1 by 7 with long division. Eventually you'll get the same answer with the same remainder i.e. it's repeating.
In a shorter example than 1/7, say 1/3,
1. you'd try to divide 1 into 3 and it's 0 times with 1 left over (0.), then
2. divide 10 into 3 and see that it's 3 times with one left over (0.3), then
3. divide 10 into 3 and see that it's 3 times with one left over (0.33),
... and so on forever (i.e. it's repeating exactly).
