Use the 9^{th} digit 0 from dividend 124578930

$$\begin{array}{l}\phantom{512436)}00000024\phantom{17}\\512436\overline{)124578930}\\\phantom{512436)}\underline{\phantom{}1024872\phantom{99}}\\\phantom{512436)9}2209173\\\phantom{512436)}\underline{\phantom{9}2049744\phantom{9}}\\\phantom{512436)99}1594290\\\end{array}$$

Find closest multiple of 512436 to 1594290. We see that 3 \times 512436 = 1537308 is the nearest. Now subtract 1537308 from 1594290 to get reminder 56982. Add 3 to quotient.

$$\begin{array}{l}\phantom{512436)}000000243\phantom{18}\\512436\overline{)124578930}\\\phantom{512436)}\underline{\phantom{}1024872\phantom{99}}\\\phantom{512436)9}2209173\\\phantom{512436)}\underline{\phantom{9}2049744\phantom{9}}\\\phantom{512436)99}1594290\\\phantom{512436)}\underline{\phantom{99}1537308\phantom{}}\\\phantom{512436)9999}56982\\\end{array}$$

Since 56982 is less than 512436, stop the division. The reminder is 56982. The topmost line 000000243 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 243.

$$\text{Quotient: }243 \text{Reminder: }56982$$
