Nice usage of hint :)

Why is expected number of steps in following example 2? Shouldn't it be 1.

m = 372 -> 37 − (2×2) -> 37 − 4 = 33; thus, since 33 is not divisible by 7, 372 is not divisible by 7.
The number of steps to get the result is 2.

And also numbers like 119 are unclear what should good solution return? [-7,1]
