924 divided by 6. Help please, thank you

Answers

924 / 6 = 154

4 in to 9 is 2, put the 2 right above the 9. 4x2=8,9-8=1, bring down the 2 in 924.
12 into 4 is 3, 3x4=12, 12-12=0, bring down the 4 in 924. 4 into 4 is 1, 4x1=4, 4-4=0. That means there is no remainder!
Hope I helped! :-)

the answer of that is 154
