We look at the division of 163203 by 4 
Let's see how many times 4 fits into 163203.

Let's proceed to step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 4

Going ahead to step 2:
When dividing 16 by 4, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 16 from 16 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 4

Step 3:
When dividing 3 by 4, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 3, we get 3.
Take the next digit (2) from the dividend and append it to 3, then repeat: 32 / 4

Let's proceed to step 4:
The number 4 fits into 32 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 408.0
The remainder is 0 after subtracting 32 from 32.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 4

Moving on to step 5:
4 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4080.0
Subtracting 0 from 0 leaves us with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 4

On to step 6:
4 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 40800.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
When dividing 30 by 4, we get 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 40800.7
Deduct 28 from 30 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 40800.75
Subtract 20 from 20 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.

Advancing to step 9:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40800.75
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.

Going ahead to step 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 40800.75
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.

After the division, we end up with 40800.75 and a remainder of 0.0.
