I can’t actually identify the insect from the photo. These are the larvae of an insect that apparently travelled with the roots of the plant you divided. 

I would remove it from the pot, wash the pot in a weak bleach solution - say 5%. Also, drench the plant and roots in soapy water. 

After replanting you may have to drench the plant again if you see new emergence, but the soapy water should kill the larvae. 

Or - Just try drenching the plant and soil with soapy water first to see if that works. 

They do look like springtails. You could still use the soapy water drench. Then be sure to let the soil dry out between waterings. 

Sansevieria are in the cacti family and need very little water. You can getaway with watering it once a month or even less.
