11512 octal to binary

Here we will show you how to convert the octal number 11512 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 11512 from octal to binary are explained below.

Step 1)
Multiply the last digit in 11512 by 8⁰, multiply the second to last digit in 11512 by 8¹, multiply the third to last digit in 11512 by 8², multiply the fourth to last digit in 11512 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
1 × 8¹ = 8
5 × 8² = 320
1 × 8³ = 512
1 × 8⁴ = 4096

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

2 + 8 + 320 + 512 + 4096 = 4938

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.

4938 ÷ 2 = 2469 with 0 remainder
2469 ÷ 2 = 1234 with 1 remainder
1234 ÷ 2 = 617 with 0 remainder
617 ÷ 2 = 308 with 1 remainder
308 ÷ 2 = 154 with 0 remainder
154 ÷ 2 = 77 with 0 remainder
77 ÷ 2 = 38 with 1 remainder
38 ÷ 2 = 19 with 0 remainder
19 ÷ 2 = 9 with 1 remainder
9 ÷ 2 = 4 with 1 remainder
4 ÷ 2 = 2 with 0 remainder
2 ÷ 2 = 1 with 0 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 11512 octal to binary:

11512 octal = 1001101001010 binary
