why is 4 divided by 1.5 is 2.66666666667, as there is the same remainder every time there should be the same quotient too. Why is 7 there in between when every remainder is divisible by 6???

Answer:
Most calculators can only show a certain amount of number so, instead of showing an endless number of 6's, which calculators can't do, they just round 6 up to 7. If a number is in decimal form, the number might not always be exact. If you want the an exact answer, fractions are the way to go.
