Division techniques

Several techniques can be used when dividing by a single digit whole number. Two commonly used methods are:

  • Using factors
  • General method

Using factors

Divide \(1920\) by \(8\) - \((1920 \div 8)\)

\(2 \times 2 \times 2 = 8\). Therefore to divide \(1920\) by \(8\) we can divide by \(2\) in each of three steps:

\[1920 \div 2 = 960\]

\[960 \div 2 = 480\]

\[480 \div 2 = 240\]

Therefore \(1920 \div 8 = 240\)

Now try the example question below.

Question

Divide \(348\) by \(6\) - \((348 \div 6)\)

\(2 \times 3 = 6\) therefore to divide \(348\) by \(6\) we can divide by \(2\) and also by \(3\):

\[348 \div 2 = 174\]

\[174 \div 3 = 58\]

Therefore \(348 \div 6 = 58\)
