We're dividing 561915 by 18 
We're looking to find how many times 18 goes into 561915.

Step 1:
The number 18 fits into 5 0 times, leaving 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.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 18

Step 2:
If we divide 56 by 18, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 54 from 56, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 18

Let's proceed to step 3:
When dividing 21 by 18, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 31.0
If we subtract 18 from 21, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 18

Advancing to step 4:
39 divided by 18 is 2 with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 312.0
If we subtract 36 from 39, we get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 18

Let's proceed to step 5:
If we divide 31 by 18, we get 1 and a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 3121.0
Subtract 18 from 31 to get 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 18

On to step 6:
When dividing 135 by 18, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 31217.0
Deduct 126 from 135 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.

Let's proceed to step 7:
90 divided by 18 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 31217.5
Subtracting 90 from 90 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 8:
The number 18 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31217.5
Subtract 0 from 0 to 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.

Advancing to step 9:
18 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 31217.5
If we take 0 away from 0, we end up 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.

The final outcome is 31217.5, with a leftover of 0.0.
