We divide 485851 by 18
Our goal is to divide 485851 by 18.

Going ahead to step 1:
If we divide 4 by 18, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 18

Advancing to step 2:
If we divide 48 by 18, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 36 from 48 and we're left with 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 18

Advancing to step 3:
125 divided by 18 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 108 from 125 to get 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 18

On to step 4:
If we divide 178 by 18, we get 9 and a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 269.0
If we take 162 away from 178, we end up with 16.
Fetch the next digit (5) from the dividend, attach it to 16 and continue: 165 / 18

On to step 5:
If we divide 165 by 18, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 2699.0
Subtracting 162 from 165 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 18

Advancing to step 6:
When dividing 31 by 18, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 26991.0
The remainder is 13 after subtracting 18 from 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
When dividing 130 by 18, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 26991.7
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 26991.72
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
If we divide 40 by 18, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 26991.722
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 26991.722 and a remainder of 0.0004.
