Importing an XML and using columns to make calculations

I need a help, I'm importing NFE xml, and I'm using the QTDA field to make a calculation, except that the quantity field in xml is composed in this way, 360.0000 and when I import that field, it is 3600000 because I am turning to decimal in the code, and also use this QTDA column to make a calculation by Ex. QTDA / QTDA column. EMB. in case it would be 3600000/2 = 1,800,000.00 but this is wrong this result the correct result should be 180 and the QTDA field should return from XML 360 and not 3600000 as it is returning. How can I resolve this?
