Let's divide 805359 by 18
We want to figure out the number of times 805359 can be divided by 18.

On to step 1:
The number 18 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 18

On to step 2:
The number 18 fits into 80 4 times, leaving a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 72 from 80, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 18

Advancing to step 3:
If we divide 85 by 18, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 44.0
If we subtract 72 from 85, we get 13.
Bring next digit (3) of the dividend behind the 13 and repeat the process: 133 / 18

Moving on to step 4:
If we divide 133 by 18, we get 7 and a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 447.0
The remainder is 7 after subtracting 126 from 133.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 18

Step 5:
The number 18 fits into 75 4 times, leaving a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4474.0
If we subtract 72 from 75, we get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 18

Going ahead to step 6:
If we divide 39 by 18, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 44742.0
Deduct 36 from 39 and we're left 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.

Moving on to step 7:
18 goes into 30 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 44742.1
If we take 18 away from 30, 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.

Going ahead to step 8:
If we divide 120 by 18, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 44742.16
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.

Moving on to step 9:
18 goes into 120 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 44742.166
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.

The final result is 44742.166 with a remainder of 0.0012.
