You can use long division. There are 0 5's in 4, so put a 0. Then put the demical point next. Bring the 3 down. How many 5's are in 43? 8. Put 8 next to the right of the decimal point. 3 is a remainder. Bring down the 5. That makes 35. There are 7 5's in 35, so you put 7 next to the 8. 0.87 is the answer. There is no remainder, so you do not have to worry about anything like that.
