551159 divided by 18 
Let's see how many times 18 fits into 551159.

Advancing to step 1:
18 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 18

Let's proceed to step 2:
If we divide 55 by 18, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 54 from 55 to get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 18

Let's proceed to step 3:
The number 18 fits into 11 0 times, leaving a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 11 after subtracting 0 from 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 18

Let's proceed to step 4:
If we divide 111 by 18, we get 6 and a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 306.0
If we subtract 108 from 111, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 18

Advancing to step 5:
35 divided by 18 is 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 3061.0
If we take 18 away from 35, we end up with 17.
Include the next digit (9) from the dividend after 17, then repeat: 179 / 18

Step 6:
18 goes into 179 9 times with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 30619.0
If we subtract 162 from 179, we 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.

Let's proceed to step 7:
170 divided by 18 is 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 30619.9
Subtracting 162 from 170 leaves us 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.

Moving on to step 8:
18 goes into 80 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 30619.94
Subtract 72 from 80 to 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.

On 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: 30619.944
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 result is 30619.944 with a remainder of 0.0008.
