209543 divided by 20 
Let's see how many times 20 fits into 209543.

Going ahead to step 1:
2 divided by 20 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 20

Advancing to step 2:
20 divided by 20 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 20 from 20.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 20

Going ahead to step 3:
20 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 20

Step 4:
95 divided by 20 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we subtract 80 from 95, we get 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 20

Going ahead to step 5:
20 goes into 154 7 times with a remainder of 14.
The next digit of our result is 7. 
Result so far: 1047.0
The remainder is 14 after subtracting 140 from 154.
Grab the next digit (3) from the dividend, add it to 14, then carry on: 143 / 20

On to step 6:
When dividing 143 by 20, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 10477.0
The remainder is 3 after subtracting 140 from 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
When dividing 30 by 20, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 10477.1
If we take 20 away from 30, we end up 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:
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: 10477.15
Subtracting 100 from 100 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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10477.15
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 10:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10477.15
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.

In conclusion, the division gives 10477.15 with a balance of 0.0.
