We look at the division of 203386 by 4 
Let's see how many times 4 fits into 203386.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 4

On to step 2:
If we divide 20 by 4, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 20 from 20 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

On to step 3:
When dividing 3 by 4, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 50.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 4

Advancing to step 4:
33 divided by 4 is 8 with a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 508.0
Deduct 32 from 33 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

On to step 5:
18 divided by 4 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 5084.0
If we subtract 16 from 18, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 4

Step 6:
4 goes into 26 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 50846.0
If we subtract 24 from 26, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
4 goes into 20 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 50846.5
Subtracting 20 from 20 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:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 50846.5
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.

On to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 50846.5
Subtract 0 from 0 to 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.

The final result is 50846.5 with a remainder of 0.0.
