365643 divided by 18 
We're looking to find how many times 18 goes into 365643.

Going ahead to step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 18

Let's proceed to step 2:
The number 18 fits into 36 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 36 from 36.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 18

Advancing to step 3:
18 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
If we take 0 away from 5, we end up with 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 18

Moving on to step 4:
When dividing 56 by 18, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 203.0
The remainder is 2 after subtracting 54 from 56.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 18

Moving on to step 5:
The number 18 fits into 24 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 2031.0
Subtract 18 from 24 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 18

On to step 6:
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: 20313.0
Subtract 54 from 63 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
If we divide 90 by 18, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 20313.5
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 18 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20313.5
Subtracting 0 from 0 leaves us 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.

Advancing to step 9:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20313.5
If we subtract 0 from 0, we get 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 final result is 20313.5 with a remainder of 0.0.
