To do scientific notation, all you have to do is take the decimal and move it over until you only have one number in front of it, then write x10^the number of spaces the decimal moved. For example 630,000 would be 6.3x10^5 because you moved the decimal over 5 times.
You divide 346 by 1,000 and get .346.
