\begin{array}{l}\phantom{83)}\phantom{1}\\83\overline{)25451}\\\end{array}
Use the 1^{st} digit 2 from dividend 25451
\begin{array}{l}\phantom{83)}0\phantom{2}\\83\overline{)25451}\\\end{array}
Since 2 is less than 83, use the next digit 5 from dividend 25451 and add 0 to the quotient
\begin{array}{l}\phantom{83)}0\phantom{3}\\83\overline{)25451}\\\end{array}
Use the 2^{nd} digit 5 from dividend 25451
\begin{array}{l}\phantom{83)}00\phantom{4}\\83\overline{)25451}\\\end{array}
Since 25 is less than 83, use the next digit 4 from dividend 25451 and add 0 to the quotient
\begin{array}{l}\phantom{83)}00\phantom{5}\\83\overline{)25451}\\\end{array}
Use the 3^{rd} digit 4 from dividend 25451
\begin{array}{l}\phantom{83)}003\phantom{6}\\83\overline{)25451}\\\phantom{83)}\underline{\phantom{}249\phantom{99}}\\\phantom{83)99}5\\\end{array}
Find closest multiple of 83 to 254. We see that 3 \times 83 = 249 is the nearest. Now subtract 249 from 254 to get reminder 5. Add 3 to quotient.
\begin{array}{l}\phantom{83)}003\phantom{7}\\83\overline{)25451}\\\phantom{83)}\underline{\phantom{}249\phantom{99}}\\\phantom{83)99}55\\\end{array}
Use the 4^{th} digit 5 from dividend 25451
\begin{array}{l}\phantom{83)}0030\phantom{8}\\83\overline{)25451}\\\phantom{83)}\underline{\phantom{}249\phantom{99}}\\\phantom{83)99}55\\\end{array}
Since 55 is less than 83, use the next digit 1 from dividend 25451 and add 0 to the quotient
\begin{array}{l}\phantom{83)}0030\phantom{9}\\83\overline{)25451}\\\phantom{83)}\underline{\phantom{}249\phantom{99}}\\\phantom{83)99}551\\\end{array}
Use the 5^{th} digit 1 from dividend 25451
\begin{array}{l}\phantom{83)}00306\phantom{10}\\83\overline{)25451}\\\phantom{83)}\underline{\phantom{}249\phantom{99}}\\\phantom{83)99}551\\\phantom{83)}\underline{\phantom{99}498\phantom{}}\\\phantom{83)999}53\\\end{array}
Find closest multiple of 83 to 551. We see that 6 \times 83 = 498 is the nearest. Now subtract 498 from 551 to get reminder 53. Add 6 to quotient.
\text{Quotient: }306 \text{Reminder: }53
Since 53 is less than 83, stop the division. The reminder is 53. The topmost line 00306 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 306.
