Given:
Dividend = 
Divisor = 
The long division is shown in the attachment.
Step 1: we need to divide with we first multiply with 3x we get the remainder as 
Quotient as 3x.
Step 2: Now the dividend is and divisor now we will multiply with -5 we get the remainder as 0 and Quotient as
Hence Quotient is and remainder is 0.
The correct answer would be 8
