Show me the standard algorithm for 72 divided by 4

72/4 4 goes into 72 how many times? start by seeing how many times 4 goes into 7, 4 goes into 7 once. this leaves a remainder of 3 now drop down the 2 (you are dividing the entire number, 72, one number at a time.) since you dropped the two you now have 32, how many times does 4 go into 32? 4x8 is 32. your first number 1 and your second number 8 together makes 18. therefore 4 goes into 72 18 times with no remainder
