Division 

An  instruction  containing  the  operation  "

÷÷÷÷

"  directs  the  computer  to  divide  the  contents  of  A 

register  (dividend)  by  the  contents  of  the  selected  register  (divisor)  and  is  executed  in  two 
phases: 
 
1ST PHASE 

Transfer the contents  of the addressed  register to M, while  retaining them 
in the original register. 

 

 

2ND PHASE 

Divide  the  contents  of  A  by  the  contents  of  M,  obtaining  in  A  the  quotient 
truncated  according  to  the  setting  of  the  Decimal  Wheel.  The  decimally 
correct fractional remainder is in R. M contains the divisor.

An example of using this instruction manually would be (assume the dividend (7.00) is in the 
b (B/) register and the divisor (3.00) is in the B register):  
Transfer the dividend to the A register by depressing keys “B/

“. . . . . . . . . . . . . . . . . .  b

  

Divide the dividend by the divisor by. depressing keys B

The quotient will print automatically only when the instructionis performed manually. 2.33 A

 

It should be noted that the remainder is in the R register and will be printed by depressing the
