      @Siddharth Shah yeah It created a confusion among students so I changed the thumbnail , On internet if you search long divison symbol you also get square root one. So both are correct.

    Great video and I like when people encourage rounding to do calculation in the head like you do. Just a little note, at 4:40 you claim that error decreases by rounding up one number and down the other. That is only true when doing approximation for multiplication, for approximation of divisions it reduces error if you round the numbers the same way but it increases if you round them in different direction.
    PS: I love the last part about the cyclic behaviour of the decimals.
