Converting from decimal to binary is a fundamental skill in computer programming and digital electronics. Binary numbers are used extensively in these fields because they represent data using only two digits (0 and 1), which can be easily processed by computers. In this article, we will provide a step-by-step guide on how to convert from decimal to binary.

Step 1: Write Down the Decimal Number

The first step in converting from decimal to binary is to write down the decimal number that you want to convert. For example, if you want to convert the decimal number 25 to binary, write down 25.

Step 2: Divide by 2

Divide the decimal number by 2. Write down the quotient (the result of the division) and the remainder (the leftover amount). For example, if you divide 25 by 2, the quotient is 12 and the remainder is 1.

Step 3: Repeat the Process

Repeat the division process with the quotient until you get a quotient of 0. For example, if you divide 12 by 2, the quotient is 6 and the remainder is 0. If you divide 6 by 2, the quotient is 3 and the remainder is 0. If you divide 3 by 2, the quotient is 1 and the remainder is 1. Finally, if you divide 1 by 2, the quotient is 0 and the remainder is 1.

Step 4: Write the Remainders in Reverse Order

Write the remainders in reverse order to get the binary number. For example, if the remainders are 1, 0, 0, 1, then the binary number is 10011. This is the binary representation of the decimal number 25.

Step 5: Check Your Work

To check your work, convert the binary number back to decimal using the following formula:

Decimal = (bn * 2^n) + (bn-1 * 2^(n-1)) + … + (b1 * 2^1) + (b0 * 2^0)

where bn is the nth digit of the binary number (counting from the right) and n is the total number of digits in the binary number. For example, if the binary number is 10011, then n is 5 and:

Decimal = (1 * 2^4) + (0 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 16 + 0 + 0 + 2 + 1 = 19

Therefore, the decimal number 25 has been correctly converted to the binary number 10011.

In conclusion, converting from decimal to binary is a simple process that can be easily learned with practice. By following these step-by-step instructions, you can convert any decimal number to binary with ease.
