Let's divide 223691 by 18
Our goal is to divide 223691 by 18.

On to step 1:
18 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 18

Let's proceed to step 2:
If we divide 22 by 18, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 18 away from 22, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 18

Advancing to step 3:
43 divided by 18 is 2 with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 7 after subtracting 36 from 43.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 18

On to step 4:
If we divide 76 by 18, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Deduct 72 from 76 and we're left with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 18

On to step 5:
18 can be fit into 49 2 times, resulting in a remainder of 13.
The next digit of our result is 2. 
Result so far: 1242.0
Deduct 36 from 49 and we're left with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 18

Step 6:
18 goes into 131 7 times with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 12427.0
Subtract 126 from 131 to 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.

Moving on to step 7:
The number 18 fits into 50 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 12427.2
If we subtract 36 from 50, 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.

Going ahead to step 8:
140 divided by 18 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 12427.27
The remainder is 14 after subtracting 126 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 9:
18 can be fit into 140 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 12427.277
Subtract 126 from 140 to 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.

The final outcome is 12427.277, with a leftover of 0.0014.
