Question 105

A programmer is writing an algorithm to perform integer division using repeated subtraction. The subroutine is shown in Figure 1.

SUBROUTINE divide(x, y)
  p ← x
  q ← 0
  WHILE p ≥ y DO
    p ← p - y
    q ← q + 1
  ENDWHILE
  OUTPUT q
ENDSUBROUTINE

The identifier for the variable q in Figure 1 is not a good choice.

State a better identifier for this variable that makes the algorithm easier to read and understand.
