Let's divide 212243 by 18
We're looking to find how many times 18 goes into 212243.

Going ahead to step 1:
If we divide 2 by 18, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 18

Step 2:
18 goes into 21 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 18 away from 21, we end up with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 18

Let's proceed to step 3:
When dividing 32 by 18, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
The remainder is 14 after subtracting 18 from 32.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 18

Step 4:
18 goes into 142 7 times with a remainder of 16.
Record the quotient 7 as the next digit in the result. 
Result so far: 117.0
Subtract 126 from 142 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 18

Let's proceed to step 5:
The number 18 fits into 164 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1179.0
Deduct 162 from 164 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 18

Going ahead to step 6:
18 goes into 23 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 11791.0
If we subtract 18 from 23, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
18 goes into 50 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 11791.2
Subtracting 36 from 50 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
140 divided by 18 is 7 with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11791.27
If we subtract 126 from 140, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
If we divide 140 by 18, we get 7 and a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 11791.277
If we take 126 away from 140, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 11791.277, with a leftover of 0.0014.
