    we have to divide 7 by 5 ....so first of all multiply 5 by 1 write 1 in the quotient..now write 5 underneath 7 , now subtract 5 from 7 your remainder is 2 ..after that you can divide it further, then use decimal ...putting a decimal will bring a zero in front of remainder 2 it will become 20 ///now multiply 5 by4 you'll get 20 and subtract 20 from 20 your division is over since remainder is zero ...okay?
