We divide 493544 by 20
Let's see how many times 20 fits into 493544.

Advancing 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
Deduct 0 from 4 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 20

Moving on to step 2:
The number 20 fits into 49 2 times, leaving a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 49 to get 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 20

Going ahead to step 3:
20 goes into 93 4 times with a remainder of 13.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 80 from 93 and we're left with 13.
Take the next digit (5) from the dividend and append it to 13, then repeat: 135 / 20

Advancing to step 4:
If we divide 135 by 20, we get 6 and a remainder of 15.
Write down 6 as next digit of the result. 
Result so far: 246.0
Subtracting 120 from 135 leaves us with 15.
Fetch the next digit (4) from the dividend, attach it to 15 and continue: 154 / 20

Advancing to step 5:
The number 20 fits into 154 7 times, leaving a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 2467.0
Deduct 140 from 154 and we're left with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 20

On to step 6:
When dividing 144 by 20, we get 7 with a remainder of 4.
The next digit of our result is 7. 
Result so far: 24677.0
If we take 140 away from 144, 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.

Moving on to step 7:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 24677.2
The remainder is 0 after subtracting 40 from 40.
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 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 24677.2
If we subtract 0 from 0, 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.

On to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 24677.2
Deduct 0 from 0 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.

In conclusion, the division gives 24677.2 with a balance of 0.0.
