803989 divided by 18 
Our goal is to divide 803989 by 18.

Moving on to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 18

Moving on to step 2:
When dividing 80 by 18, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 72 from 80 and we're left with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 18

On to step 3:
18 can be fit into 83 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 72 from 83 to get 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 18

Step 4:
119 divided by 18 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 446.0
Subtract 108 from 119 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 18

Let's proceed to step 5:
118 divided by 18 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 4466.0
Deduct 108 from 118 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 18

Going ahead to step 6:
When dividing 109 by 18, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 44666.0
Deduct 108 from 109 and we're left 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.

Step 7:
10 divided by 18 is 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 44666.0
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 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 44666.05
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.

Let's proceed to step 9:
18 goes into 100 5 times with a remainder of 10.
The next digit of our result is 5. 
Result so far: 44666.055
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 44666.055 with a balance of 0.001.
