Solve 1800div40

$$1800 \div 40$$

Evaluate

$$45$$

Steps For Long Division Method

Use the 1^{st} digit 1 from dividend 1800

$$\begin{array}{l}\phantom{40)}\phantom{1}\\40\overline{)1800}\\\end{array}$$

Since 1 is less than 40, use the next digit 8 from dividend 1800 and add 0 to the quotient

$$\begin{array}{l}\phantom{40)}0\phantom{2}\\40\overline{)1800}\\\end{array}$$

Use the 2^{nd} digit 8 from dividend 1800

$$\begin{array}{l}\phantom{40)}0\phantom{3}\\40\overline{)1800}\\\end{array}$$

Since 18 is less than 40, use the next digit 0 from dividend 1800 and add 0 to the quotient

$$\begin{array}{l}\phantom{40)}00\phantom{4}\\40\overline{)1800}\\\end{array}$$

Use the 3^{rd} digit 0 from dividend 1800

$$\begin{array}{l}\phantom{40)}00\phantom{5}\\40\overline{)1800}\\\end{array}$$

Find closest multiple of 40 to 180. We see that 4 \times 40 = 160 is the nearest. Now subtract 160 from 180 to get reminder 20. Add 4 to quotient.

$$\begin{array}{l}\phantom{40)}004\phantom{6}\\40\overline{)1800}\\\phantom{40)}\underline{\phantom{}160\phantom{9}}\\\phantom{40)9}20\\\end{array}$$

Use the 4^{th} digit 0 from dividend 1800

$$\begin{array}{l}\phantom{40)}004\phantom{7}\\40\overline{)1800}\\\phantom{40)}\underline{\phantom{}160\phantom{9}}\\\phantom{40)9}200\\\end{array}$$

Find closest multiple of 40 to 200. We see that 5 \times 40 = 200 is the nearest. Now subtract 200 from 200 to get reminder 0. Add 5 to quotient.

$$\begin{array}{l}\phantom{40)}0045\phantom{8}\\40\overline{)1800}\\\phantom{40)}\underline{\phantom{}160\phantom{9}}\\\phantom{40)9}200\\\phantom{40)}\underline{\phantom{9}200\phantom{}}\\\phantom{40)9999}0\\\end{array}$$

Since 0 is less than 40, stop the division. The reminder is 0. The topmost line 0045 is the quotient. Remove all zeros at the start of the quotient to get the actual quotient 45.

$$\text{Quotient: }45 \text{Reminder: }0$$

Factor

$$3^{2}\times 5$$
