22644 divided by 18 
We're looking to find how many times 18 goes into 22644.

Going ahead 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
Subtracting 0 from 2 leaves us with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 18

Step 2:
If we divide 22 by 18, we get 1 and a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 18 from 22 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 18

Going ahead to step 3:
18 can be fit into 46 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 36 from 46 leaves us with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 18

Let's proceed to step 4:
If we divide 104 by 18, we get 5 and a remainder of 14.
The next digit of our result is 5. 
Result so far: 125.0
Subtracting 90 from 104 leaves us with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 18

Going ahead to step 5:
18 can be fit into 144 8 times, resulting in a remainder of 0.
The next digit of our result is 8. 
Result so far: 1258.0
The remainder is 0 after subtracting 144 from 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 6:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1258.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1258.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 1258.0, and the remainder is 0.0.
