Divide Whole Numbers: example 1.66

Let's rewrite the problem to set it up for long division.	$241\overline{)\mathrm{74,521}}$
First we try to divide 241 into 7. Since that won’t work, we try 241 into 74. That still won’t work, so we try 241 into 745. Since 2 divides into 7 three times, we try 3. Since $3\times 241=723$, we write the 3 over the 5 in 745. Note that 4 would be too large because $4\times 241=964$, which is greater than 745.
Multiply the 3 by 241 and subtract this product from 745.
Now bring down the 2 and repeat these steps. 241 does not divide into 222. We write a 0 over the 2 as a placeholder and then continue.
Now bring down the 1 and repeat these steps. Try 9. Since $9\times 241=\mathrm{2,169}$, we write the 9 over the 1. Multiply the 9 by 241 and subtract this product from 2,221.
There are no more numbers to bring down, so we are finished. The remainder is 52. So $\mathrm{74,521}÷241$ is 309 with a remainder of 52.
Check by multiplying.

Sometimes it might not be obvious how many times the divisor goes into digits of the dividend. We will have to guess and check numbers to find the greatest number that goes into the digits without exceeding them.
