57305 octal to binary

Here we will show you how to convert the octal number 57305 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 57305 from octal to binary are explained below.

Step 1)
Multiply the last digit in 57305 by 8⁰, multiply the second to last digit in 57305 by 8¹, multiply the third to last digit in 57305 by 8², multiply the fourth to last digit in 57305 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
0 × 8¹ = 0
3 × 8² = 192
7 × 8³ = 3584
5 × 8⁴ = 20480

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

5 + 0 + 192 + 3584 + 20480 = 24261

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.

24261 ÷ 2 = 12130 with 1 remainder
12130 ÷ 2 = 6065 with 0 remainder
6065 ÷ 2 = 3032 with 1 remainder
3032 ÷ 2 = 1516 with 0 remainder
1516 ÷ 2 = 758 with 0 remainder
758 ÷ 2 = 379 with 0 remainder
379 ÷ 2 = 189 with 1 remainder
189 ÷ 2 = 94 with 1 remainder
94 ÷ 2 = 47 with 0 remainder
47 ÷ 2 = 23 with 1 remainder
23 ÷ 2 = 11 with 1 remainder
11 ÷ 2 = 5 with 1 remainder
5 ÷ 2 = 2 with 1 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 57305 octal to binary:

57305 octal = 101111011000101 binary
