We're dividing 5399 by 18 
We're looking to find how many times 18 goes into 5399.

Advancing to step 1:
If we divide 5 by 18, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 18

On to step 2:
The number 18 fits into 53 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 17 after subtracting 36 from 53.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 18

Let's proceed to step 3:
18 can be fit into 179 9 times, resulting in a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 162 from 179 leaves us with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 18

Going ahead to step 4:
If we divide 179 by 18, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 299.0
If we take 162 away from 179, we end up 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.

Advancing to step 5:
170 divided by 18 is 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 299.9
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 6:
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: 299.94
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
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: 299.944
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.

After the division, we end up with 299.944 and a remainder of 0.0008.
