This is how 51 Shaktipeeths were established

 Lord Shiva was married to Sati, the daughter of Prajapati Daksha, son of Brahma. After some time Daksha was made the ruler of the whole universe. This made Daksha proud. He began to consider himself the best. When Lord Shiva did not bow down to himself in a yajna, Daksha uttered many abusive words to him. Daksha cursed Shiva that he would not get his share in the Dev Yagya.

  Hearing this, Nandi also cursed Daksha that the mouth with which he is blaspheming Shiva will turn into that of a goat.

  After some time Daksha organized a grand yagya. All the gods and goddesses were called in it, but the arrogant Daksha expelled Shiva from that yagya. Somehow when Sati came to know about this, she asked Shiva for permission to go to that yagya. At first Shiva explained to her but when she did not agree, he allowed Sati to go there. When Sati reached her father's house, Daksha turned her eyes away from her. Sati became angry after not seeing Shiva's part in the yagya and started saying bad things to everyone.

  Hearing this, Daksha also started condemning Shiva. Hearing this, Sati was very sad and she burnt her body with Yogagri. Seeing this, the ganas of Shiva attacked Daksha Yagya but the gods drove them away from there. He went to Shiva and narrated the whole incident. Hearing this, Shiva got very angry. He uprooted one of his hairs and hit it on the ground, from which Virbhadra and Mahakali appeared. Shiva ordered both of them to destroy Daksha's yajna. He destroyed Daksha's yajna within a moment and Virbhadra cut off Daksha's head and threw him into the Yagya Kund.

  Seeing this, there was a stir among the gods and they started praising Shiva. Praising him, he gave life to everyone and by putting the head of a goat on Daksha's body, he also made him alive. Later, with the permission of Shiva, Daksha completed his yajna. Shiva started roaming in the whole universe carrying the dead body of his beloved wife.

  The whole creation started burning due to his majesty. Then Vishnu cut Sati's body into 51 pieces with his Sudarshan Chakra. Wherever these pieces fell, Shaktipeeths were established.

  Then the whole body of Sati was cut off and the Lord was very sad and went to Kailas and took samadhi in solitude.
