Years ago, when I began this great deciphering adventure, I was
stuck with trying to visibly reverse numbers that ended in zero until I worked
out to change the cell format to *text* which meant that the now visible
number with the zero at the beginning had no number properties so I had remember
to type in the calculated outcome and in order to show you why, where and how
all this is important, I give you a look at the non-formatted cell which shows
85 which then loses the legitimacy of being the reversed number 580:

Here is the completed outcome:

3229÷6=538.166666666667

Round off to nearest whole number: 538

538÷6=89.6666666666667

Round off to nearest whole number: 90

Stephen Hawking died on Pi Day 3-14-2018 and this brilliant man inspired me to
add Pi to my calculations:

3229÷3.1415926535=1027.82262251684

Round off to nearest whole number: 1028

1028÷3.1415926535=327.222563006289

Round off to nearest whole number: 327

327÷3.1415926535=104.087354436859

Round off to nearest whole number: 104
