how to get interval mathematically

If I have n of elements (e.g n=100)

int n=100; 
int[] n=new  int[n];
System.out.print("Enter something:");
Integer input =(Integer) System.console().readLine();

And I divide n to intervals (e.g partitioning=10)

So in this case I have 10 intervals: [0,9],[10,19],[20,29]...[90,100]

The question is:

If user input a element, how to get its interval? I want to know if this number located in first 10 or in second ten or third...

But without using switch or for loop. I want it mathematically, with equations.

Just divide the number by 10 using Integer Division and add 1:

bucket number = n / 10 + 1
