![2:25=0+(2/(25)) write 0, add next digit 20:25=0+((20)/(25)) write 0, add next digit 207:25=8+(7/(25)) write 8, add next digit 75:25=3+(0/(25)) write 3, add next digit 1:25=0+(1/(25)) write 0, add next digit [no more digits ⇒ add “.”&0] 10:25=0+((10)/(25)) write 0, add next digit 100:25=4+(0/(25)) write 4, done](Q48753.png)
