We're dividing 209403 by 10 
Let's see how many times 10 fits into 209403.

On to step 1:
If we divide 2 by 10, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 10

Going ahead to step 2:
10 goes into 20 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 20 from 20.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 10

Advancing to step 3:
9 divided by 10 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 9, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 10

On to step 4:
If we divide 94 by 10, we get 9 and a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 209.0
Deduct 90 from 94 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 10

Going ahead to step 5:
10 goes into 40 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2094.0
Subtracting 40 from 40 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 10

On to step 6:
If we divide 3 by 10, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 20940.0
The remainder is 3 after subtracting 0 from 3.
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:
30 divided by 10 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 20940.3
Subtracting 30 from 30 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 8:
10 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20940.3
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.

On to step 9:
If we divide 0 by 10, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20940.3
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.

The quotient of the division is 20940.3, and the remainder is 0.0.
