Once you attempt the question then PrepInsta explanation will be displayed.
Let us take exponents 0, 1, 2, 3, ....one by one to "17"
For example, if we take exponent "0" for 17, we get 17⁰ = 1
Here 1 is less than the divisor 16 and 1 can not be divided by 16.
If the dividend is less than the divisor, then that dividend itself to be considered as "Remainder"
So, if 17⁰ is divided by 16, we get the remainder "1"
