having problem in dividing a large number with 5 then follow this steps
Dividing a large number by five is actually very simple. All you do is multiply the numbar by 2 and move the decimal point
105 / 5
1-->: 105 * 2 = 2102-->: Move the decimal: 21.0 or just 21
2978 / 5
1-->: 2978 * 2 = 59562-->: 595.6

MAGIC OF MATHS
8 1 6
3 5 7
4 9 2
IF U ADD all rows, columns and diagonals sum to 15.
If you read the rows as NUMBERS, forwards and backwards, and square them, then
8162 + 3572 + 4922 = 6182 + 7532 + 2942. Magic?
