There are two ways to divide degrees, minutes and seconds. One is to multiply the degree by 60 to become minutes, then multiply the sum of the minutes by 60 to become seconds, and then remove the number to be divided. The obtained seconds can be divided by 1 minute every 60 seconds, or can be directly divided by dividing value, minute and second. First divide the degree by the number to be divided, then turn the remaining degree that is not divided equally into points, and then divide the fraction by this divisor.
