Set Up Division: First, set up the division: 31.572 ÷ 18.Divide 31 by 18: Start dividing 18 into 31, which goes 1 time. 1 times 18 is 18.Subtract and Bring Down: Subtract 18 from 31 to get 13. Bring down the 5 to make it 135.Repeat Division: 18 goes into 135 about 7 times because 7 times 18 is 126.Continue Division: Subtract 126 from 135 to get 9. Bring down the 7 to make it 97.Final Steps: 18 goes into 97 about 5 times because 5 times 18 is 90.Subtract 90 from 97 to get 7. Since there are no more digits to bring down, we can add a zero and bring it down to make it 70.18 goes into 70 about 3 times because 3 times 18 is 54.Subtract 54 from 70 to get 16. Add another zero and bring it down to make it 160.18 goes into 160 about 8 times because 8 times 18 is 144.Subtract 144 from 160 to get 16. Since the remainder is repeating, we can stop here.

31.572 ÷18

Set Up Division: First, set up the division: $31.572 \div 18$ .
Divide $31$ by $18$ : Start dividing $18$ into $31$ , which goes $1$ time. $1$ times $18$ is $18$ .
Subtract and Bring Down: Subtract $18$ from $31$ to get $13$ . Bring down the $5$ to make it $135$ .
Repeat Division: $18$ goes into $135$ about $7$ times because $7$ times $18$ is $126$ .
Continue Division: Subtract $126$ from $135$ to get $9$ . Bring down the $7$ to make it $97$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ . Subtract $90$ from $97$ to get $7$ . Since there are no more digits to bring down, we can add a zero and bring it down to make it $70$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ . Subtract $90$ from $97$ to get $7$ . Since there are no more digits to bring down, we can add a zero and bring it down to make it $70$ . $18$ goes into $70$ about $97$ $2$ times because $97$ $2$ times $18$ is $97$ $5$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ . Subtract $90$ from $97$ to get $7$ . Since there are no more digits to bring down, we can add a zero and bring it down to make it $70$ . $18$ goes into $70$ about $97$ $2$ times because $97$ $2$ times $18$ is $97$ $5$ . Subtract $97$ $5$ from $70$ to get $97$ $8$ . Add another zero and bring it down to make it $97$ $9$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ . Subtract $90$ from $97$ to get $7$ . Since there are no more digits to bring down, we can add a zero and bring it down to make it $70$ . $18$ goes into $70$ about $97$ $2$ times because $97$ $2$ times $18$ is $97$ $5$ . Subtract $97$ $5$ from $70$ to get $97$ $8$ . Add another zero and bring it down to make it $97$ $9$ . $18$ goes into $97$ $9$ about $5$ $2$ times because $5$ $2$ times $18$ is $5$ $5$ .
Final Steps: $18$ goes into $97$ about $5$ times because $5$ times $18$ is $90$ . Subtract $90$ from $97$ to get $7$ . Since there are no more digits to bring down, we can add a zero and bring it down to make it $70$ . $18$ goes into $70$ about $97$ $2$ times because $97$ $2$ times $18$ is $97$ $5$ . Subtract $97$ $5$ from $70$ to get $97$ $8$ . Add another zero and bring it down to make it $97$ $9$ . $18$ goes into $97$ $9$ about $5$ $2$ times because $5$ $2$ times $18$ is $5$ $5$ . Subtract $5$ $5$ from $97$ $9$ to get $97$ $8$ . Since the remainder is repeating, we can stop here.
