well need to calculate A/B

well the units are:                         The rest of
C0 = int (A/B)           ....................  R0 = A - C0 * B

the first decimal is

C1 = int ( (A - B * C0 ) *10 / B )   .........  C1 = int ( R0*10 / B)
.............  R1 = R0*10 - C1*B

C2 = int ( R1 * 10 /  B )


Cn= int ( 10 * R(n-1) / B) .................... Rn = 10*R(n-1) - Cn*B




Exemple: 7 / 11

C0 = 0    R0 = 7
C1 = int (70/11)   = 6           R1= 70-6*11 = 4
C2 = int (40/11) =  3            R2 = 7
C3 = 70/11 = 6                 R3 = 4
C4 = 40/11 = 3                R4 = 7

etc ...  with a loop willbe easy




so 7 / 11   =   0.6309




hope this will help you ....
