I’m reading about using long divison but I don’t really understand this sentence. I’m reading the solution so here this is saying ” Estimate 7(divison bar, 161 divide by 7) 161 by first estimating 7/16 and writing the result in the tens place of the quotient. Since 7 times 2 equals to 14, there are at least 2 sevens in 16. What does that last sentence mean?
