\begin{array}{l}\phantom{890)}\phantom{1}\\890\overline{)4539}\\\end{array}
Use the 1^{st} digit 4 from dividend 4539
\begin{array}{l}\phantom{890)}0\phantom{2}\\890\overline{)4539}\\\end{array}
Since 4 is less than 890, use the next digit 5 from dividend 4539 and add 0 to the quotient
\begin{array}{l}\phantom{890)}0\phantom{3}\\890\overline{)4539}\\\end{array}
Use the 2^{nd} digit 5 from dividend 4539
\begin{array}{l}\phantom{890)}00\phantom{4}\\890\overline{)4539}\\\end{array}
Since 45 is less than 890, use the next digit 3 from dividend 4539 and add 0 to the quotient
\begin{array}{l}\phantom{890)}00\phantom{5}\\890\overline{)4539}\\\end{array}
Use the 3^{rd} digit 3 from dividend 4539
\begin{array}{l}\phantom{890)}000\phantom{6}\\890\overline{)4539}\\\end{array}
Since 453 is less than 890, use the next digit 9 from dividend 4539 and add 0 to the quotient
\begin{array}{l}\phantom{890)}000\phantom{7}\\890\overline{)4539}\\\end{array}
Use the 4^{th} digit 9 from dividend 4539
\begin{array}{l}\phantom{890)}0005\phantom{8}\\890\overline{)4539}\\\phantom{890)}\underline{\phantom{}4450\phantom{}}\\\phantom{890)99}89\\\end{array}
Find closest multiple of 890 to 4539. We see that 5 \times 890 = 4450 is the nearest. Now subtract 4450 from 4539 to get reminder 89. Add 5 to quotient.
\text{Quotient: }5 \text{Reminder: }89
Since 89 is less than 890, stop the division. The reminder is 89. The topmost line 0005 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 5.
