We look at the division of 789415 by 18 
Our goal is to divide 789415 by 18.

On to step 1:
If we divide 7 by 18, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 18

Advancing to step 2:
78 divided by 18 is 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 72 from 78 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 18

Step 3:
18 goes into 69 3 times with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 15 after subtracting 54 from 69.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 18

Step 4:
If we divide 154 by 18, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 438.0
If we take 144 away from 154, we end up with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 18

Let's proceed to step 5:
18 goes into 101 5 times with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 4385.0
If we take 90 away from 101, we end up with 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 18

Moving on to step 6:
When dividing 115 by 18, we get 6 with a remainder of 7.
Write down 6 as next digit of the result. 
Result so far: 43856.0
Subtract 108 from 115 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.

Moving on to step 7:
When dividing 70 by 18, we get 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 43856.3
If we subtract 54 from 70, 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.

Step 8:
The number 18 fits into 160 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 43856.38
Subtracting 144 from 160 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.

On to step 9:
18 can be fit into 160 8 times, resulting in a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 43856.388
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.

The final outcome is 43856.388, with a leftover of 0.0016.
