7522 octal to binary

Here we will show you how to convert the octal number 7522 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 7522 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7522 by 8⁰, multiply the second to last digit in 7522 by 8¹, multiply the third to last digit in 7522 by 8², multiply the fourth to last digit in 7522 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
2 × 8¹ = 16
5 × 8² = 320
7 × 8³ = 3584

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

2 + 16 + 320 + 3584 = 3922

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.

3922 ÷ 2 = 1961 with 0 remainder
1961 ÷ 2 = 980 with 1 remainder
980 ÷ 2 = 490 with 0 remainder
490 ÷ 2 = 245 with 0 remainder
245 ÷ 2 = 122 with 1 remainder
122 ÷ 2 = 61 with 0 remainder
61 ÷ 2 = 30 with 1 remainder
30 ÷ 2 = 15 with 0 remainder
15 ÷ 2 = 7 with 1 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 7522 octal to binary:

7522 octal = 111101010010 binary
