10min help with binary math! ASAP

ive spent the last 30min just reading through tutorials and i just cant get it! :mad:

Binary Division

1. 1001011 / 110 = 1100
2. 1111100 / 1101 = 1001
3. 11000101 / 10110 = 1000
4. 11101101 / 100010 = 110
5. 111011110 / 10010 = 11010

Floating point

1. (0.1*100)+(0.1011*100) = ?
2. (0.10111*101)-(0.10011*101) = ?
3. (0.11*100)*(0.1001*100)
4. (0.11*101)/(0.1*11) = ?

for both sets of questions i have to show the working out which is the reason i cant use a calculator! i have the answers for the first set i just need to do the working out! :mad:

(answers have to be converted back into standard form!)

It's easy :

1. 1001011 / 110 = 1100
75 / 6 = 12

2. 1111100 / 1101 = 1001
124 / 13 = 9

3. 11000101 / 10110 = 1000
197 / = 22 = 8

4. 11101101 / 100010 = 110
237 / 34 = 6

5. 111011110 / 10010 = 11010
478 / 18 = 26

I don't do floating point though.

pho surley thats wrong? i'm not on about converting it back to denary then to binary i'm on about working it out straight from binary

i only supplied the answer as i did them on a calculator earlier!

Dividing binary is just repeated subtraction. Just show your working line after line until you have the quotient and the remainder worked out :/

can you extend on that and show me an example?
