Answer:
20.51282
Explanation:
1. Starting by the smallest number that can be divided. 80÷39 equals to 2.
2. Now we write 2 in the answer line.
3. Multiply the result by 39. That makes us 78.
4. Now we write 78 under 800.
5. Subtract the numbers (80-78) and now we have 2.
6. Bring 0 next to our substracted number (2) so that will make it 20.
7. Divide the subtracted number with our initial value (39). That will make us a decimal number (0.512) but we will note the 0 except if you want to make it detailed then note 20.51282
8. Add the 0 next to the 2 that we writed in the start above.
9. Write the remainder (20) next to the quotient.
10. The result is 20 or to be exact 20.51282 and we have a remainder of 20.
