We look at the division of 253457 by 18 
We're looking to find how many times 18 goes into 253457.

Step 1:
2 divided by 18 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 18

Going ahead to step 2:
18 goes into 25 1 times with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 18 from 25, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 18

Step 3:
73 divided by 18 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 72 from 73 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 18

Advancing to step 4:
18 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 140.0
Subtract 0 from 14 to get 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 18

Let's proceed to step 5:
18 can be fit into 145 8 times, resulting in a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 1408.0
Subtract 144 from 145 to get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 18

Let's proceed to step 6:
18 can be fit into 17 0 times, resulting in a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 14080.0
Subtract 0 from 17 to get 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:
When dividing 170 by 18, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 14080.9
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14080.94
If we take 72 away from 80, 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.

Going ahead to step 9:
When dividing 80 by 18, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14080.944
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 quotient of the division is 14080.944, and the remainder is 0.0008.
