\begin{array}{l}\phantom{1609)}\phantom{1}\\1609\overline{)4569}\\\end{array}
Use the 1^{st} digit 4 from dividend 4569
\begin{array}{l}\phantom{1609)}0\phantom{2}\\1609\overline{)4569}\\\end{array}
Since 4 is less than 1609, use the next digit 5 from dividend 4569 and add 0 to the quotient
\begin{array}{l}\phantom{1609)}0\phantom{3}\\1609\overline{)4569}\\\end{array}
Use the 2^{nd} digit 5 from dividend 4569
\begin{array}{l}\phantom{1609)}00\phantom{4}\\1609\overline{)4569}\\\end{array}
Since 45 is less than 1609, use the next digit 6 from dividend 4569 and add 0 to the quotient
\begin{array}{l}\phantom{1609)}00\phantom{5}\\1609\overline{)4569}\\\end{array}
Use the 3^{rd} digit 6 from dividend 4569
\begin{array}{l}\phantom{1609)}000\phantom{6}\\1609\overline{)4569}\\\end{array}
Since 456 is less than 1609, use the next digit 9 from dividend 4569 and add 0 to the quotient
\begin{array}{l}\phantom{1609)}000\phantom{7}\\1609\overline{)4569}\\\end{array}
Use the 4^{th} digit 9 from dividend 4569
\begin{array}{l}\phantom{1609)}0002\phantom{8}\\1609\overline{)4569}\\\phantom{1609)}\underline{\phantom{}3218\phantom{}}\\\phantom{1609)}1351\\\end{array}
Find closest multiple of 1609 to 4569. We see that 2 \times 1609 = 3218 is the nearest. Now subtract 3218 from 4569 to get reminder 1351. Add 2 to quotient.
\text{Quotient: }2 \text{Reminder: }1351
Since 1351 is less than 1609, stop the division. The reminder is 1351. The topmost line 0002 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 2.
