Here you see step by step process of decimal to binary number conversion. We have to follow some steps one by one those are
1) We have to divide the decimal number by 2 repeatedly, until the quotient of zero is obtained.
2) The remainders are noted down for each of the division steps.
3) Then the column of the remainder is read in reverse order . That means we have to count those reminder from bottom to top.
In bellow I give you an example to show the process
Let we have to convert 2510 in binary. We know the base of binary is 2. So we have to divide the decimal number by 2.
So the equivalent number 2510 = 110012
So I think the above example will clear the process of decimal to binary number conversion.
