#### For calculation of remainder and quotient
-Since calculation of modulo is subtracion of `v` from `u` until `u` is strictly smaller than `v`, procedure to follow `u - v` is as follows: (__Assumption: INstruction pointer points to index 1__)

+1. While current cell value is not `0`, move right.
+2. If current cell value is `0`, go left. If it is `1`:
+ a. Go right. Go right. If it is `1`:
+ i. Go right until current cell is `B`.
+ ii. Move left until current cell is `1`.
+ iii. Mark it as `X`.
+ iv. Move left until current cell is `B`.
+ v. MOve right, make `1` as `B`. Goto step #1.
#### To find if the number is prime
-For an input `num`, the first step is to make a copy of $\lfloor\dfrac{num}{2}\rfloor$ start reading the tape from the beginning. (__Assumption: INstruction pointer points to index 0__)

1. For every second `1` encountered, mark it as `D`.
2. Move right until `B` is found.
