Divide using the repeated subtraction method.
\[20 \div 4\]

Hint: In this question, first of all subtract 4 from 20. Then subtract 4 from the obtained value repeatedly until we get 0 remainder. The number of times subtracted 4 is the required answer i.e., quotient of \[20 \div 4\].

Complete step-by-step answer:
Given \[20 \div 4\]
Here we can solve this by the repeated subtraction method. So, we need to subtract 4 from 20 until we get 0.
 Step 1: subtracting 4 from 20
              20 – 4 = 16
Step 2: subtracting 4 from 16
              16 – 4 = 12
Step 3: subtracting 4 from 12
              12 – 4 = 8
Step 4: subtracting 4 from 8
              8 – 4 = 4
Step 5: subtracting 4 from 4
              4 – 4 = 0
So, we have subtracted 5 times 4 from 20 to get 0 remainder.
Thus, \[20 \div 4\] is equal to 5.

Note: Here we can check our answer by dividend = divisor \[ \times \] quotient + remainder. Where dividend is 20, divisor is 4, quotient is 5 and remainder is 0.
