223 can be converted easily from decimal to binary. The methods mentioned below will help us convert the number. Let’s see how it is done.

Expansion Method: Let us see the step-by-step process of converting 223 using the expansion method.

Step 1 - Figure out the place values: In the binary system, each place value is a power of 2. Therefore, in the first step, we will ascertain the powers of 2. 20 = 1 21 = 2 22 = 4 23 = 8 24 = 16 25 = 32 26 = 64 27 = 128 28 = 256 Since 256 is greater than 223, we stop at 27 = 128.

Step 2 - Identify the largest power of 2: In the previous step, we stopped at 27 = 128. This is because in this step, we have to identify the largest power of 2, which is less than or equal to the given number, 223. Since 27 is the number we are looking for, write 1 in the 27 place. Now the value of 27, which is 128, is subtracted from 223. 223 - 128 = 95.

Step 3 - Identify the next largest power of 2: In this step, we need to find the largest power of 2 that fits into the result of the previous step, 95. The next largest power of 2 is 26, which is equal to 64. Now, we have to write 1 in the 26 place. And then subtract 64 from 95. 95 - 64 = 31.

Step 4 - Continue the process: Repeat the steps to find the largest power of 2 that fits into the current difference. Continue this until the remainder is 0. 31 - 16 = 15 15 - 8 = 7 7 - 4 = 3 3 - 2 = 1 1 - 1 = 0

Step 5 - Write the values in reverse order: We now write the numbers upside down to represent 223 in binary. Therefore, 11011111 is 223 in binary.

Grouping Method: In this method, we divide the number 223 by 2. Let us see the step-by-step conversion.

Step 1 - Divide the given number 223 by 2. 223 / 2 = 111. Here, 111 is the quotient and 1 is the remainder.

Step 2 - Divide the previous quotient (111) by 2. 111 / 2 = 55. Here, the quotient is 55 and the remainder is 1.

Step 3 - Repeat the previous step. 55 / 2 = 27. Now, the quotient is 27, and 1 is the remainder.

Step 4 - Repeat the previous step. 27 / 2 = 13. Now, the quotient is 13, and 1 is the remainder.

Step 5 - Repeat the previous step. 13 / 2 = 6. Now, the quotient is 6, and 1 is the remainder.

Step 6 - Repeat the previous step. 6 / 2 = 3. Now, the quotient is 3, and 0 is the remainder.

Step 7 - Repeat the previous step. 3 / 2 = 1. Now, the quotient is 1, and 1 is the remainder.

Step 8 - Repeat the previous step. 1 / 2 = 0. Here, the remainder is 1. And we stop the division here because the quotient is 0.

Step 9 - Write down the remainders from bottom to top. Therefore, 223 (decimal) = 11011111 (binary).
