2. Divide the number of seconds by 60 to convert seconds to minutes. Every 60 seconds a full minute has passed. Dividing a number tells you how many times one number fits in the other.
For example, 14 minutes and 45 seconds equals 14.75 minutes, because 45/60 equals 0.75. Divide the number of minutes by 60, the total number of minutes in an hour. For example, convert 14.75 minutes to a percentage by dividing 14.75 by 60, which equals about 0.246, or 24.6 percent.
