Augmentin oral dose is 40 mg/kg/day divided BID for 10 days. How often should it be administered?

Dosing frequency is guided by spreading the total daily dose over the day to keep drug levels in the therapeutic range. Here, 40 mg/kg per day is given as two equal doses, so you administer 20 mg/kg every 12 hours. The reason this works well is that amoxicillin-clavulanate has a relatively short duration of action in the body, so regular dosing every ~12 hours maintains effective levels against the bacteria. Giving it once daily would let drug levels drop below therapeutic between doses, risking subtherapeutic exposure, while more frequent dosing isn’t indicated by this regimen. Therefore, it should be administered twice daily.
