We divide 486634 by 18
Our goal is to divide 486634 by 18.

On to step 1:
18 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 18

Let's proceed to step 2:
18 can be fit into 48 2 times, resulting in a remainder of 12.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 36 from 48, we get 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 18

Let's proceed to step 3:
18 goes into 126 7 times with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
Subtract 126 from 126 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 18

On to step 4:
If we divide 6 by 18, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 270.0
If we subtract 0 from 6, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 18

On to step 5:
18 goes into 63 3 times with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 2703.0
Subtracting 54 from 63 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 18

Going ahead to step 6:
94 divided by 18 is 5 with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 27035.0
Subtract 90 from 94 to 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.

Let's proceed to step 7:
When dividing 40 by 18, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 27035.2
If we take 36 away from 40, we end up 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 goes into 40 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 27035.22
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.

The final result is 27035.22 with a remainder of 0.004.
