807591 ÷ 18 
Let's see how many times 18 fits into 807591.

Advancing to step 1:
18 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 18

Advancing to step 2:
80 divided by 18 is 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 72 from 80 to get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 18

On to step 3:
87 divided by 18 is 4 with a remainder of 15.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 72 from 87 and we're left with 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 18

Going ahead to step 4:
155 divided by 18 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 448.0
Subtracting 144 from 155 leaves us with 11.
Grab the next digit (9) from the dividend, add it to 11, then carry on: 119 / 18

Advancing to step 5:
18 can be fit into 119 6 times, resulting in a remainder of 11.
Write down 6 as next digit of the result. 
Result so far: 4486.0
Deduct 108 from 119 and we're left with 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 18

Moving on to step 6:
18 goes into 111 6 times with a remainder of 3.
The next digit of our result is 6. 
Result so far: 44866.0
If we take 108 away from 111, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 18 is 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 44866.1
Subtracting 18 from 30 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 8:
18 can be fit into 120 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 44866.16
If we subtract 108 from 120, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 18 fits into 120 6 times, leaving a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 44866.166
If we take 108 away from 120, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 44866.166 with a balance of 0.0012.
