We're dividing 368631 by 18 
We want to divide 368631 by 18.

On to step 1:
3 divided by 18 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 18

Let's proceed to step 2:
If we divide 36 by 18, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 36 from 36 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 18

Going ahead to step 3:
18 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 18

Advancing to step 4:
When dividing 86 by 18, we get 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 204.0
The remainder is 14 after subtracting 72 from 86.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 18

Advancing to step 5:
18 can be fit into 143 7 times, resulting in a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 2047.0
If we subtract 126 from 143, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 18

Step 6:
18 can be fit into 171 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 20479.0
Deduct 162 from 171 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
The number 18 fits into 90 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20479.5
If we subtract 90 from 90, 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.

Going ahead to step 8:
18 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20479.5
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.

Let's proceed to step 9:
When dividing 0 by 18, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20479.5
The remainder is 0 after subtracting 0 from 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 outcome is 20479.5, with a leftover of 0.0.
