210943 ÷ 18 
We want to figure out the number of times 210943 can be divided by 18.

Step 1:
The number 18 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 18

Going ahead to step 2:
18 can be fit into 21 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 18 from 21, we get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 18

Let's proceed to step 3:
When dividing 30 by 18, we get 1 with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 12 after subtracting 18 from 30.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 18

Let's proceed to step 4:
129 divided by 18 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 117.0
Deduct 126 from 129 and we're left with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 18

On to step 5:
18 goes into 34 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1171.0
Subtract 18 from 34 to get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 18

Moving on to step 6:
The number 18 fits into 163 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 11719.0
Subtracting 162 from 163 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 18, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11719.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 18 is 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11719.05
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
When dividing 100 by 18, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 11719.055
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Our division results in 11719.055 with a remaining 0.001.
