We divide 543865 by 20
We want to divide 543865 by 20.

Advancing to step 1:
If we divide 5 by 20, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 20

Advancing to step 2:
20 goes into 54 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 54 to get 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 20

Going ahead to step 3:
When dividing 143 by 20, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 27.0
Subtracting 140 from 143 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 20

Let's proceed to step 4:
The number 20 fits into 38 1 times, leaving a remainder of 18.
The next digit of our result is 1. 
Result so far: 271.0
If we subtract 20 from 38, we get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 20

Advancing to step 5:
186 divided by 20 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 2719.0
Subtract 180 from 186 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 20

Moving on to step 6:
20 goes into 65 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 27193.0
If we take 60 away from 65, we end up 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.

On to step 7:
The number 20 fits into 50 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 27193.2
If we subtract 40 from 50, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 27193.25
If we take 100 away from 100, we end up 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27193.25
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27193.25
If we take 0 away from 0, we end up 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.

After the division, we end up with 27193.25 and a remainder of 0.0.
