We're dividing 496945 by 18 
We're looking to find how many times 18 goes into 496945.

Let's proceed to step 1:
The number 18 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 18

On to step 2:
The number 18 fits into 49 2 times, leaving a remainder of 13.
The next digit of our result is 2. 
Result so far: 2.0
If we take 36 away from 49, we end up with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 18

Let's proceed to step 3:
The number 18 fits into 136 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 126 from 136 and we're left with 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 18

On to step 4:
When dividing 109 by 18, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 276.0
Subtract 108 from 109 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 18

Advancing to step 5:
The number 18 fits into 14 0 times, leaving a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 2760.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 18

Moving on to step 6:
The number 18 fits into 145 8 times, leaving a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 27608.0
Subtracting 144 from 145 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
18 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 27608.0
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 8:
If we divide 100 by 18, we get 5 and a remainder of 10.
The next digit of our result is 5. 
Result so far: 27608.05
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
18 can be fit into 100 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 27608.055
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 27608.055 with a balance of 0.001.
