How to remove beginning zeros / avoid scientific notation?

Hi guys,

I have a column “EQUIPMENT” with values “000000003000393052, 000000003000397538 …”.

I want to remove all the zeros in the beginnings. My solution is changing this column from string to double and then change it from double to string.

However, the values become scientific notation when they become double.

Can you guys teach me how to remove the beginning zeros or teach me how to avoid scientific notation? Thanks!
