7705 octal to binary

Here we will show you how to convert the octal number 7705 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 7705 from octal to binary are explained below.

Step 1)
Multiply the last digit in 7705 by 8⁰, multiply the second to last digit in 7705 by 8¹, multiply the third to last digit in 7705 by 8², multiply the fourth to last digit in 7705 by 8³, and so on, until all the digits are used:

5 × 8⁰ = 5
0 × 8¹ = 0
7 × 8² = 448
7 × 8³ = 3584

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

5 + 0 + 448 + 3584 = 4037

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.

4037 ÷ 2 = 2018 with 1 remainder
2018 ÷ 2 = 1009 with 0 remainder
1009 ÷ 2 = 504 with 1 remainder
504 ÷ 2 = 252 with 0 remainder
252 ÷ 2 = 126 with 0 remainder
126 ÷ 2 = 63 with 0 remainder
63 ÷ 2 = 31 with 1 remainder
31 ÷ 2 = 15 with 1 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 7705 octal to binary:

7705 octal = 111111000101 binary
