Hi,
I’m not sure about where to put decimal line in Flag Pole method, as I could not find any instructions to do this in your book.
According to your step instruction step number 5 (If you cross the decimal line in the dividend add a decimal point) but where do I put decimal line in the first place? Is it always between tens and units? For example exercise no.1, 64924/13, Do I place decimal line between 2 and 4 digits?
Anyway, Keep up good work!
Kind Regards

Where you draw the line will depend on the number of digits in the flag. If the flag has one digit, then you will draw the decimal line after one digit from the right.
In your example 1 is the pole and 3 is the flag. The flag is a one digit number which is 3. So you will draw the line between 2 and 4 in 64924 (i.e 64924).
If you divide 64924 by 224 then where you draw the line will depend on how you create the flag and the pole.
If in 224 you make 22 the pole and 4 the flag, then you will draw the line between 2 and 4 in 64924 (i.e 64924) because the flag 4 is only one digit.
If in 224 you make 2 the pole and 24 the flag, then you will draw the line between 9 and 2 in 64924 (i.e 64924) because the flag 24 is two digits.
Hope this clarifies.
