42166 octal to binary




Here we will show you how to convert the octal number 42166 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 42166 from octal to binary are explained below.

Step 1)
Multiply the last digit in 42166 by 8⁰, multiply the second to last digit in 42166 by 8¹, multiply the third to last digit in 42166 by 8², multiply the fourth to last digit in 42166 by 8³, and so on, until all the digits are used:

6 × 8⁰ = 6
6 × 8¹ = 48
1 × 8² = 64
2 × 8³ = 1024
4 × 8⁴ = 16384

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

6 + 48 + 64 + 1024 + 16384 = 17526

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.

17526 ÷ 2 = 8763 with 0 remainder
8763 ÷ 2 = 4381 with 1 remainder
4381 ÷ 2 = 2190 with 1 remainder
2190 ÷ 2 = 1095 with 0 remainder
1095 ÷ 2 = 547 with 1 remainder
547 ÷ 2 = 273 with 1 remainder
273 ÷ 2 = 136 with 1 remainder
136 ÷ 2 = 68 with 0 remainder
68 ÷ 2 = 34 with 0 remainder
34 ÷ 2 = 17 with 0 remainder
17 ÷ 2 = 8 with 1 remainder
8 ÷ 2 = 4 with 0 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 42166 octal to binary:

42166 octal = 100010001110110 binary
