630921 ÷ 18 
Our goal is to divide 630921 by 18.

Moving on to step 1:
6 divided by 18 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 18

Advancing to step 2:
18 can be fit into 63 3 times, resulting in a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 54 from 63, we get 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 18

Going ahead to step 3:
The number 18 fits into 90 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 35.0
Subtract 90 from 90 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 18

Going ahead to step 4:
9 divided by 18 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 350.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 18

Moving on to step 5:
92 divided by 18 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 3505.0
Deduct 90 from 92 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 18

On to step 6:
If we divide 21 by 18, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 35051.0
The remainder is 3 after subtracting 18 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
30 divided by 18 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 35051.1
If we subtract 18 from 30, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 8:
120 divided by 18 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 35051.16
Deduct 108 from 120 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 35051.166
Subtracting 108 from 120 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 35051.166 with a balance of 0.0012.
