  I know how to do long division. I do something like it but skip the subtraction part and just use reasoning the entire time to get my answer. I surprisingly rarely get it wrong unless I'm dividing a number in the thousands with a single digit number that isn't 2. I'm too lazy to use calculators anyway.
  
  
  
  The third elementary school I went to used this. I thought it was a new high tech, innovative way of multiplication since the school was the first school I went to that wasn't dirt poor and had 'smart boards' and 'whiteboards' instead of 'chalkboards' and 'projectors'.
  
  I tried to do it and failed miserably. The traditional style was so much easier to do imo, and nobody in the school knew how to do it aside from the teachers and thought it was way too hard to do.
  
  Skip forward a year to middle school. Majority of the people that learned the lattice method had horrible math grades in 6th grade. Skip to 8th grade, and I find out from my math teacher that he's really pissed that the students were taught the lattice method because it's horrible and prone to error (apparently). I lol'd.

  I save lattice for only mutliplaying past 3 decimals to speed it up
  I was taught the old fashion method and lattice
  Ie 10 x 450
  Do 10 x 40 then 10 x 50 and so on
  The old fashion method is the basis for my mental math in reality

  I've never heard of the lattice method.

  Older generations normally dont know about this method since its on the newer list
  If i could save a picture in paint id show you the basis behind it

  I forgot how to do long division. Mainly because you don't really need it so much these days, especially in college. Whenever my professors say that he won't allow calculators on an exam, it's because you don't need to do many calculations anyway; they're usually only very basic (and a lot of physics professor like you to estimate).
  
  But yeah, every once in awhile, I'll revisit that part of my brain.
