Reformatting the input :

Changes made to your input should not affect the solution:

(1): "4.58257569" was replaced by "(458257569/100000000)".

Step  1  :

            458257569
 Simplify   —————————
            100000000

Equation at the end of step  1  :

        458257569
  -1 -  ————————— ÷ 2
        100000000

Step  2  :

         458257569      
 Divide  —————————  by  2
         100000000      

Equation at the end of step  2  :

        458257569
  -1 -  —————————
        200000000

Step  3  :

Rewriting the whole as an Equivalent Fraction :

 3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  200000000  as the denominator :

           -1     -1 • 200000000
     -1 =  ——  =  ——————————————
           1        200000000   

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

 3.2       Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

 -1 • 200000000 - (458257569)     -658257569
 ————————————————————————————  =  ——————————
          200000000               200000000 

Final result :

  -658257569            
  —————————— = -3.29129 
  200000000
