The initial length of the ribbon is 51 meters, which is equivalent to 51 * 100 = 5100 centimeters.
If each piece measures 15 centimeters, then cutting 100 pieces would require 100 * 15 = 1500 centimeters of ribbon.
Therefore, the remaining length of the ribbon is 5100 - 1500 = 3600 centimeters.
To convert this back to meters, we divide by 100, so the remaining length is 3600 / 100 = 36 meters.
#### 36
The answer is: 36
