What is 3231 divided by 35?

Answer 1

92.3143

Answer 2

It's easy enough to type it into a calculator & read the answer:

92.314285714285714...

...but this gives no real insight into the numbers.

Better to factor:

35 = 5*7. That one's easy.

3231 is a multiple of 3 because the digit sum (3+2+3+1 = 9) is a multiple of 3.

3231 = 3*1077

1077 is also a multiple of 3 (same reason)

1077 = 3*359

359 turns out to be prime (you can test division by 3,5,7,11,13,17; no need to try larger prime factors because 19*19 = 361 > 359)

Putting it together:

3231 / 35 = (3*3*359) / (5*7)

No common factors, so already in lowest terms as a fraction.

Done.
