Diluting HCl issues ?

Remember that when you have a concentration, you actually have a measure of whatever it is you have dissolved in water. So 2.00 moldm-3 is 2 moles of HCL per 2dm3 of water. If you want to make the concentration smaller, you need to alter that ratio so that there's now more water compared with HCL than in the original. Do you see where I'm going with this?

Using volumetric pipette, measure a known quantity (25cm^3 say) into a 250 cm^3 volumetric flask. Using distilled water, fill the volumetric flask. this dilutes to 1/10th original concentration. Repea
t it once with a clean pipette to get to 1/100th of the concentration

I understand this but how would I do this practically? Would I need to take 25cm3 of the first sample out the volumetric flask then place it in another flask and fill it with distilled water to 250cm3 ?
