Let's divide 250397 by 18
We're looking to find how many times 18 goes into 250397.

Advancing to step 1:
18 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 18

Advancing to step 2:
When dividing 25 by 18, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 18 from 25 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 18

Step 3:
18 goes into 70 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 54 from 70 and we're left with 16.
Grab the next digit (3) from the dividend, add it to 16, then carry on: 163 / 18

Step 4:
When dividing 163 by 18, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 139.0
If we subtract 162 from 163, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 18

Let's proceed to step 5:
18 can be fit into 19 1 times, resulting in a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1391.0
Subtracting 18 from 19 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 18

Going ahead to step 6:
If we divide 17 by 18, we get 0 and a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 13910.0
Deduct 0 from 17 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
18 goes into 170 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 13910.9
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 8:
If we divide 80 by 18, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 13910.94
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 13910.944
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 13910.944, with a leftover of 0.0008.
