                                   Instructions

              This spreadsheet finds the decimal expansion of a
              fraction of your choosing, to as many decimal
              places as desired. The initial fraction is shown in
              blue above, and can be changed by highlighting
              either numerator or denominator and replacing
              them with whole number alternatives.

              There ought to be enough decimal places shown to
              detect any patterns (eg for recurring decimals).
              If you want still more, highlight the formulas in
              cells CZ4-CZ6 and select cells to the right. Then
              Under the EDIT menu, select FILL > RIGHT.

              To see how the spreadsheet works, study the
              formulas carefully; you might be able to see that
              the long division algorithm is being used. The small
              numbers under the decimal expansion show the
              successive numbers being divided by the
              denominator each time.
