631811 ÷ 18 
Our goal is to divide 631811 by 18.

Moving on to step 1:
If we divide 6 by 18, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 18

Going ahead to step 2:
If we divide 63 by 18, we get 3 and a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 54 away from 63, we end up with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 18

On to step 3:
18 goes into 91 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Deduct 90 from 91 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 18

Going ahead to step 4:
18 can be fit into 18 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 351.0
The remainder is 0 after subtracting 18 from 18.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 18

Let's proceed to step 5:
18 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 3510.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 18

Advancing to step 6:
The number 18 fits into 11 0 times, leaving a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 35100.0
Deduct 0 from 11 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
18 goes into 110 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 35100.6
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 18, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 35100.61
Subtract 18 from 20 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 18, we get 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 35100.611
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 35100.611 with a balance of 0.0002.
