Answer Explanation
Sol. This expansions nothing but the decimal expansion of any number in any base to a base 10.
For eg are have a number 66 and we want to convert it into a binary number (base2)
So we first divide 66 by 2 then again divide the quotient obtained by 2 then again the quotient by 2 and so on.
S 66=(1000010)
2 This is successive division (we are dividing quotients obtained again by 2.
In short form
we write all the remainders together
