To convert the decimal number 25 to binary,
Divide 25 by 2:
Quotient: 12
Remainder: 1
Divide the quotient (12) by 2:
Quotient: 6
Remainder: 0
Divide the new quotient (6) by 2:
Quotient: 3
Remainder: 0
Divide the new quotient (3) by 2:
Quotient: 1
Remainder: 1
Divide the final quotient (1) by 2:
Quotient: 0
Remainder: 1
Now, read the remainders in reverse order (bottom to top): 11001
So, the decimal number 25 is equal to the binary number 11001.
