52121 octal to binary

Here we will show you how to convert the octal number 52121 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 52121 from octal to binary are explained below.

Step 1)
Multiply the last digit in 52121 by 8⁰, multiply the second to last digit in 52121 by 8¹, multiply the third to last digit in 52121 by 8², multiply the fourth to last digit in 52121 by 8³, and so on, until all the digits are used:

1 × 8⁰ = 1
2 × 8¹ = 16
1 × 8² = 64
2 × 8³ = 1024
5 × 8⁴ = 20480

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

1 + 16 + 64 + 1024 + 20480 = 21585

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.

21585 ÷ 2 = 10792 with 1 remainder
10792 ÷ 2 = 5396 with 0 remainder
5396 ÷ 2 = 2698 with 0 remainder
2698 ÷ 2 = 1349 with 0 remainder
1349 ÷ 2 = 674 with 1 remainder
674 ÷ 2 = 337 with 0 remainder
337 ÷ 2 = 168 with 1 remainder
168 ÷ 2 = 84 with 0 remainder
84 ÷ 2 = 42 with 0 remainder
42 ÷ 2 = 21 with 0 remainder
21 ÷ 2 = 10 with 1 remainder
10 ÷ 2 = 5 with 0 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 52121 octal to binary:

52121 octal = 101010001010001 binary
