361684 ÷ 18 
We want to figure out the number of times 361684 can be divided by 18.

Step 1:
18 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 18

On to step 2:
18 can be fit into 36 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 36 away from 36, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 18

On to step 3:
If we divide 1 by 18, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 18

Going ahead to step 4:
18 can be fit into 16 0 times, resulting in a remainder of 16.
The next digit of our result is 0. 
Result so far: 200.0
If we subtract 0 from 16, we get 16.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 18

Step 5:
If we divide 168 by 18, we get 9 and a remainder of 6.
The next digit of our result is 9. 
Result so far: 2009.0
The remainder is 6 after subtracting 162 from 168.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

Step 6:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 20093.0
Deduct 54 from 64 and we're left 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.

Let's proceed to step 7:
When dividing 100 by 18, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 20093.5
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 20093.55
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 20093.55 with a remainder of 0.01.
