Let's divide 542496 by 20
We're looking to find how many times 20 goes into 542496.

Let's proceed to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 20

On to step 2:
The number 20 fits into 54 2 times, leaving a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 40 from 54 and we're left with 14.
Bring next digit (2) of the dividend behind the 14 and repeat the process: 142 / 20

Going ahead to step 3:
20 goes into 142 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtracting 140 from 142 leaves us with 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 20

Moving on to step 4:
The number 20 fits into 24 1 times, leaving a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 271.0
If we subtract 20 from 24, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 20

Step 5:
When dividing 49 by 20, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 2712.0
The remainder is 9 after subtracting 40 from 49.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 20

Moving on to step 6:
If we divide 96 by 20, we get 4 and a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 27124.0
Subtract 80 from 96 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
160 divided by 20 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 27124.8
The remainder is 0 after subtracting 160 from 160.
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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27124.8
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.

Advancing 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: 27124.8
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 final outcome is 27124.8, with a leftover of 0.0.
