# about the 3%7 remainder. how come the answer is 3 as doesn't fit into 3 should it not be 0?

unclear how 3%7 equals 3 in stead of 0

## 1 Answer

Hi Berry,

The answer is 3 because 7 does not fit into 3 as you said. Since it does not fit, you are left with everything (i.e. 3).

If you play in the playground in Xcode, you can see this yourself.

```let answer1 = 3%2 // remainder = 1.  2 fits into 3 once and you are left with 1
let answer = 3%7 // remainder = 3.  7 does not fit so you are left with everything (3)
```

I hope that helps,

Mike
