Let's divide 485970 by 18
We're looking to find how many times 18 goes into 485970.

Advancing to step 1:
4 divided by 18 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 18

Let's proceed to step 2:
18 can be fit into 48 2 times, resulting in a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 36 away from 48, we end up with 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 18

Step 3:
The number 18 fits into 125 6 times, leaving a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 17 after subtracting 108 from 125.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 18

Step 4:
18 can be fit into 179 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 269.0
Subtracting 162 from 179 leaves us with 17.
Grab the next digit (7) from the dividend, add it to 17, then carry on: 177 / 18

Advancing to step 5:
The number 18 fits into 177 9 times, leaving a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 2699.0
If we take 162 away from 177, we end up with 15.
Fetch the next digit (0) from the dividend, attach it to 15 and continue: 150 / 18

Step 6:
18 goes into 150 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 26998.0
Deduct 144 from 150 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 7:
18 can be fit into 60 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 26998.3
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
If we divide 60 by 18, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 26998.33
If we take 54 away from 60, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 26998.33 with a remainder of 0.006.
