1520÷83= 18R26
First, you have to divide it like whole numbers. Then you have 3 options:
1. Stop and turn the fraction into a remainder (R15)
2. Stop and turn the answer into a fraction by putting the remainder as the numerator and the divisor as the denominator. (3/5)
3. Add a decimal after the last digit and keep dividing until the answer is found. Feel free to add any zeros to the end.
