\begin{array}{l}\phantom{280)}\phantom{1}\\280\overline{)5880}\\\end{array}
Use the 1^{st} digit 5 from dividend 5880
\begin{array}{l}\phantom{280)}0\phantom{2}\\280\overline{)5880}\\\end{array}
Since 5 is less than 280, use the next digit 8 from dividend 5880 and add 0 to the quotient
\begin{array}{l}\phantom{280)}0\phantom{3}\\280\overline{)5880}\\\end{array}
Use the 2^{nd} digit 8 from dividend 5880
\begin{array}{l}\phantom{280)}00\phantom{4}\\280\overline{)5880}\\\end{array}
Since 58 is less than 280, use the next digit 8 from dividend 5880 and add 0 to the quotient
\begin{array}{l}\phantom{280)}00\phantom{5}\\280\overline{)5880}\\\end{array}
Use the 3^{rd} digit 8 from dividend 5880
\begin{array}{l}\phantom{280)}002\phantom{6}\\280\overline{)5880}\\\phantom{280)}\underline{\phantom{}560\phantom{9}}\\\phantom{280)9}28\\\end{array}
Find closest multiple of 280 to 588. We see that 2 \times 280 = 560 is the nearest. Now subtract 560 from 588 to get reminder 28. Add 2 to quotient.
\begin{array}{l}\phantom{280)}002\phantom{7}\\280\overline{)5880}\\\phantom{280)}\underline{\phantom{}560\phantom{9}}\\\phantom{280)9}280\\\end{array}
Use the 4^{th} digit 0 from dividend 5880
\begin{array}{l}\phantom{280)}0021\phantom{8}\\280\overline{)5880}\\\phantom{280)}\underline{\phantom{}560\phantom{9}}\\\phantom{280)9}280\\\phantom{280)}\underline{\phantom{9}280\phantom{}}\\\phantom{280)9999}0\\\end{array}
Find closest multiple of 280 to 280. We see that 1 \times 280 = 280 is the nearest. Now subtract 280 from 280 to get reminder 0. Add 1 to quotient.
\text{Quotient: }21 \text{Reminder: }0
Since 0 is less than 280, stop the division. The reminder is 0. The topmost line 0021 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 21.
