Fluently divide multi-digit numbers using the standard algorithm

What you'll learn

1. Explain the structure of the standard long division algorithm in terms of place value — each step finds the quotient digit for one place value position
2. Fluently apply the standard algorithm to divide multi-digit numbers by a 1-digit divisor, recording all steps correctly
3. Fluently apply the standard algorithm to divide multi-digit numbers by a 2-digit divisor, including estimating partial quotients when the first trial digit is too large or too small
4. Interpret the remainder in context (as a fractional part of the quotient, as a leftover quantity, or as a reason to round up)
