89,420 ÷ 27
give me a good explanation. and step by step

I'm assuming this is long division.
   
27|89,420

27 goes into 89 3 times with a remainder of 8

    _3
27|89,420
      84      (bring down the 4 from above)

27 goes into 84 3 times with a remainder of 3

    _3,3__
27|89,420
      84
        32      (once again, write the remainder and bring down the next digit)

27 goes into 32 1 time with a remainder of 5

    _3,31_
27|89,420
      84
        32
          50

27 goes into 50 1 time with a remainder of 23

so your answer is 3,311 and 23/27

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
