47442 octal to binary

Here we will show you how to convert the octal number 47442 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 47442 from octal to binary are explained below.

Step 1)
Multiply the last digit in 47442 by 8⁰, multiply the second to last digit in 47442 by 8¹, multiply the third to last digit in 47442 by 8², multiply the fourth to last digit in 47442 by 8³, and so on, until all the digits are used:

2 × 8⁰ = 2
4 × 8¹ = 32
4 × 8² = 256
7 × 8³ = 3584
4 × 8⁴ = 16384

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

2 + 32 + 256 + 3584 + 16384 = 20258

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.

20258 ÷ 2 = 10129 with 0 remainder
10129 ÷ 2 = 5064 with 1 remainder
5064 ÷ 2 = 2532 with 0 remainder
2532 ÷ 2 = 1266 with 0 remainder
1266 ÷ 2 = 633 with 0 remainder
633 ÷ 2 = 316 with 1 remainder
316 ÷ 2 = 158 with 0 remainder
158 ÷ 2 = 79 with 0 remainder
79 ÷ 2 = 39 with 1 remainder
39 ÷ 2 = 19 with 1 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 47442 octal to binary:

47442 octal = 100111100100010 binary
