89665 ÷ 18 
We're looking to find how many times 18 goes into 89665.

Moving on to step 1:
18 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 18

Step 2:
If we divide 89 by 18, we get 4 and a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 72 from 89, we get 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 18

Step 3:
If we divide 176 by 18, we get 9 and a remainder of 14.
The next digit of our result is 9. 
Result so far: 49.0
If we take 162 away from 176, we end up with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 18

On to step 4:
18 goes into 146 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 498.0
If we take 144 away from 146, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 18

On to step 5:
18 can be fit into 25 1 times, resulting in a remainder of 7.
The next digit of our result is 1. 
Result so far: 4981.0
Subtract 18 from 25 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 6:
18 goes into 70 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 4981.3
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
18 goes into 160 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 4981.38
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
160 divided by 18 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 4981.388
Subtract 144 from 160 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 4981.388 with a remainder of 0.0016.
