499605 divided by 20 
We're looking to find how many times 20 goes into 499605.

On to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

Step 2:
The number 20 fits into 49 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 40 from 49 to get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 20

On to step 3:
99 divided by 20 is 4 with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
Subtracting 80 from 99 leaves us with 19.
Grab the next digit (6) from the dividend, add it to 19, then carry on: 196 / 20

On to step 4:
The number 20 fits into 196 9 times, leaving a remainder of 16.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Deduct 180 from 196 and we're left with 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 20

Let's proceed to step 5:
20 goes into 160 8 times with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2498.0
If we subtract 160 from 160, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 20

Advancing to step 6:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 24980.0
Subtracting 0 from 5 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
20 can be fit into 50 2 times, resulting in a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 24980.2
Deduct 40 from 50 and we're left 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 8:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 24980.25
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24980.25
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24980.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 24980.25 with a balance of 0.0.
