118 306 divided by 17 265 simple calculation

I think the answer on the second floor is very confusing. This is the answer upstairs. 118 306/17 265=118 18 265=100 200 (18 2) (18 2) (60 1)=300 101 =401 Is it more convenient to decompose it this way? 118 306/17 265=118 18 265=100 200 {(10 8) (10 8) (60 5)}=100 200 {(10 8) (10 8) (60 4 1)}=100 200 {(10 10) (8 8 4) 60 1｝=100 200 (20 20 60 1)=100 200 (40 60 1)=100 200 (100 1)=300 100 1=400 1=401What a magical answer. It is actually 401. In fact, I think as long as it is convenient for calculation, there is no need to go to so much trouble. My nephew, who was in grade 3 just now, was doing calculations with me next to me. He made me laugh. He said you have to do that to calculate. I'm sweating.
