We look at the division of 63875383 by 303 
Let's see how many times 303 fits into 63875383.

Going ahead to step 1:
6 divided by 303 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 303

Moving on to step 2:
When dividing 63 by 303, we get 0 with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Fetch the next digit (8) from the dividend, attach it to 63 and continue: 638 / 303

Advancing to step 3:
303 can be fit into 638 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 606 from 638 to get 32.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 303

Step 4:
When dividing 327 by 303, we get 1 with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
Deduct 303 from 327 and we're left with 24.
Bring next digit (5) of the dividend behind the 24 and repeat the process: 245 / 303

On to step 5:
245 divided by 303 is 0 with a remainder of 245.
Record the quotient 0 as the next digit in the result. 
Result so far: 210.0
Subtracting 0 from 245 leaves us with 245.
Take the next digit (3) from the dividend and append it to 245, then repeat: 2453 / 303

Step 6:
2453 divided by 303 is 8 with a remainder of 29.
Write down 8 as next digit of the result. 
Result so far: 2108.0
If we subtract 2424 from 2453, we get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 303

On to step 7:
If we divide 298 by 303, we get 0 and a remainder of 298.
The next digit of our result is 0. 
Result so far: 21080.0
If we take 0 away from 298, we end up with 298.
Grab the next digit (3) from the dividend, add it to 298, then carry on: 2983 / 303

On to step 8:
The number 303 fits into 2983 9 times, leaving a remainder of 256.
The number 9 becomes the next digit in our result. 
Result so far: 210809.0
The remainder is 256 after subtracting 2727 from 2983.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 9:
When dividing 2560 by 303, we get 8 with a remainder of 136.
Write down 8 as next digit of the result. 
Result so far: 210809.8
If we take 2424 away from 2560, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Advancing to step 10:
When dividing 1360 by 303, we get 4 with a remainder of 148.
Use 4 as the next digit of our solution. 
Result so far: 210809.84
If we take 1212 away from 1360, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 11:
1480 divided by 303 is 4 with a remainder of 268.
Use 4 as the next digit of our solution. 
Result so far: 210809.844
Subtract 1212 from 1480 to get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

After the division, we end up with 210809.844 and a remainder of 0.0268.
