Binary dividing with a remainder

Question

How much is $\frac{101000}{1001}$ in binary? I checked in 3 sites, each displayed another result.

The result I get is 100 with a reminder of 100. Can you please try and solve it and show how you did?

Answer 1

You can always check your answer by converting to decimal and back: 101000b = 40d divided by 1001b = 9d equals 4d with remainder 4d. Converting the answer back to binary gives quotient 100b with remainder 100b. Your answer is correct.
