We look at the division of 789904 by 18 
We want to figure out the number of times 789904 can be divided by 18.

Advancing to step 1:
18 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 18

Going ahead to step 2:
18 can be fit into 78 4 times, resulting in a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 72 away from 78, we end up with 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 18

On to step 3:
If we divide 69 by 18, we get 3 and a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtract 54 from 69 to get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 18

Going ahead to step 4:
18 can be fit into 159 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 438.0
The remainder is 15 after subtracting 144 from 159.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 18

Going ahead to step 5:
18 goes into 150 8 times with a remainder of 6.
The next digit of our result is 8. 
Result so far: 4388.0
Subtracting 144 from 150 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 18

Step 6:
The number 18 fits into 64 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 43883.0
If we take 54 away from 64, we end up 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.

Moving on to step 7:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 43883.5
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.

Let's proceed to step 8:
18 goes into 100 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 43883.55
If we subtract 90 from 100, we get 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 quotient of the division is 43883.55, and the remainder is 0.01.
