We're dividing 88561 by 18 
Let's see how many times 18 fits into 88561.

Advancing to step 1:
8 divided by 18 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 18

Let's proceed to step 2:
If we divide 88 by 18, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 72 from 88 to get 16.
Append the next digit (5) from the dividend to 16 and continue with: 165 / 18

Going ahead to step 3:
The number 18 fits into 165 9 times, leaving a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 49.0
If we subtract 162 from 165, we get 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 18

On to step 4:
18 can be fit into 36 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 492.0
The remainder is 0 after subtracting 36 from 36.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 18

Advancing to step 5:
1 divided by 18 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 4920.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 6:
The number 18 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4920.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
18 goes into 100 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 4920.05
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 18 fits into 100 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 4920.055
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final result is 4920.055 with a remainder of 0.001.
