We look at the division of 788839 by 18 
We want to figure out the number of times 788839 can be divided by 18.

Moving on to step 1:
18 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 18

Moving on to step 2:
18 goes into 78 4 times with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 72 from 78 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 18

Step 3:
18 can be fit into 68 3 times, resulting in a remainder of 14.
The next digit of our result is 3. 
Result so far: 43.0
If we take 54 away from 68, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 18

Moving on to step 4:
18 can be fit into 148 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 438.0
Subtract 144 from 148 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 18

Step 5:
18 can be fit into 43 2 times, resulting in a remainder of 7.
Use 2 as the next digit of our solution. 
Result so far: 4382.0
Deduct 36 from 43 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 18

Advancing to step 6:
If we divide 79 by 18, we get 4 and a remainder of 7.
The next digit of our result is 4. 
Result so far: 43824.0
If we subtract 72 from 79, we 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.

Advancing to step 7:
The number 18 fits into 70 3 times, leaving a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 43824.3
Subtract 54 from 70 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.

Moving on to step 8:
18 goes into 160 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 43824.38
If we subtract 144 from 160, we 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.

Going ahead to step 9:
If we divide 160 by 18, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 43824.388
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.

Our division results in 43824.388 with a remaining 0.0016.
