degrees, occurrence, time, counter for occurrences, consider, attitude
度 centers on measuring or passing through intervals: degrees on a scale, occurrences counted over time, and the mental attitude or consideration one brings to a situation.
度 combines 广 (building) with an inner component that likely contributed the sound and the idea of measuring or passing. The exact historical development of the inner part is uncertain.
Under a roof 广, imagine a hand 又 holding a measuring tool over a container 凵 with a mark 一, checking degrees or counting occurrences.
For ド, picture a door under the roof: door -> ド, and each time you open it you count one occurrence.
