Known dividend+divisor+quotient+remainder =599
So according to the definition of division,
599 = dividend+divisor+quotient+remainder
= (quotient * divisor+remainder)+divisor+quotient+remainder
= (quotient+1) * divisor+remainder * 2+ quotient
Therefore, divisor =(599- quotient-remainder *2)/ (quotient+1)
=(599- 15- 12*2)/( 15+ 1)
= 35 Hope to adopt
