Taken from your example above :
10/6 = 2 (should be 1.67)
Assuming you want 2 decimal precision, then you should do the following :
10 x 100 = 1000 --> 1000/6 = 166. Then, you need to remember that this number (166) is 1.66 x 100. The next step would be to extract the integer part and the decimal part of this number to have 2 other numbers : 1 and 66. Then, in a text component, you can input the "1" as the integer part and the "66" as the decimal part after the point. to show the real number as "1"."66" .
Remember that you cannot use floating point values in PLUS1. They are all integers.
Also, make sure to use 16-bit or 32-bit data type because the first multiplication (by 100 or 1000) can increase the output a lot and you can fall into an overflow.
