Let's divide 496435 by 20
Let's see how many times 20 fits into 496435.

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
Subtract 0 from 4 to get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 20

On to step 2:
49 divided by 20 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 49 and we're left with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 20

Advancing to step 3:
If we divide 96 by 20, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
The remainder is 16 after subtracting 80 from 96.
Bring next digit (4) of the dividend behind the 16 and repeat the process: 164 / 20

On to step 4:
If we divide 164 by 20, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 248.0
If we subtract 160 from 164, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 20

Going ahead to step 5:
20 can be fit into 43 2 times, resulting in a remainder of 3.
Record the quotient 2 as the next digit in the result. 
Result so far: 2482.0
Subtract 40 from 43 to get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 20

Moving on to step 6:
When dividing 35 by 20, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 24821.0
Deduct 20 from 35 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
20 can be fit into 150 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 24821.7
Subtracting 140 from 150 leaves us 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 24821.75
If we subtract 100 from 100, we 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24821.75
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 24821.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 24821.75, and the remainder is 0.0.
