7205 octal to binary

Here we will show you how to convert the octal number 7205 to a binary number. First note that the octal number system has eight different digits (0 1 2 3 4 5 6 7) and the binary number system has only two different digits (0 and 1).

The four steps used to convert 7205 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7205 by 8⁰, multiply the second to last digit in 7205 by 8¹, multiply the third to last digit in 7205 by 8², multiply the fourth to last digit in 7205 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
0 × 8¹ = 0
2 × 8² = 128
7 × 8³ = 3584

Step 2)
Next, we add up all the products we got from Step 1, like this:

5 + 0 + 128 + 3584 = 3717

Step 3)
Now we divide the sum from Step 2 by 2. Put the remainder aside. Then divide the whole part by 2 again, and put the remainder aside again. Keep doing this until the whole part is 0.

3717 ÷ 2 = 1858 with 1 remainder
1858 ÷ 2 = 929 with 0 remainder
929 ÷ 2 = 464 with 1 remainder
464 ÷ 2 = 232 with 0 remainder
232 ÷ 2 = 116 with 0 remainder
116 ÷ 2 = 58 with 0 remainder
58 ÷ 2 = 29 with 0 remainder
29 ÷ 2 = 14 with 1 remainder
14 ÷ 2 = 7 with 0 remainder
7 ÷ 2 = 3 with 1 remainder
3 ÷ 2 = 1 with 1 remainder
1 ÷ 2 = 0 with 1 remainder

Step 4)
In the final step, we take the remainders from Step 3 and put them together in reverse order to get our answer to 7205 octal to binary:

7205 octal = 111010000101 binary
