4/86 = ≈4.65%
Rounded to 2 decimal places.
A share of 4.65% might show up when a store reports that a small number of customers returned an item, or when a survey finds that only a few people chose one answer. It describes a small part of a larger group.
To picture it quickly, think of about 5 people out of every 100. That makes it easier to see that the amount is close to, but a little less than, one in 20.
One common mix-up is treating 4.65% as if it meant 4.65 people. A percentage describes a share of a group, so the actual number of people depends on how large the group is.
