Well, I suspect it has something to do with writing out the process of 5772 / 37 as
156
______
37 | 5772
37
---
207
185
----
222

because it a) reverses the order of dividend and divisor for no good reason; b) the result goes up instead of to the right or down. Why not write it like this
5772 | 37
37 +----

instead? In fact, I think we could replace the corner with just normal slash, "/", write = to the right of the divisor and spell out the digits of the result to the right of it; the substraction chain will still go down the page.
- nh23423fefe 4y agoyou can't extend the numerator to get more places like this unless you do it upfront 5772.00000000 | 37 also polynomial division works better the other way too, i think.
- Joker_vD 4y agoSure you can: 5772 / 36 = 160,33... 36 --- 217 216 ---- 120 108 ---- 120 108 ---- ...

That's exactly the way I was taught long division (in Germany).
- skyde 4y agosame this is how i learned it in Canada public school
