We look at the division of 53253573 by 303 
Let's see how many times 303 fits into 53253573.

Step 1:
303 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 303

Advancing to step 2:
53 divided by 303 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Grab the next digit (2) from the dividend, add it to 53, then carry on: 532 / 303

Going ahead to step 3:
532 divided by 303 is 1 with a remainder of 229.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 303 from 532, we get 229.
Bring next digit (5) of the dividend behind the 229 and repeat the process: 2295 / 303

Advancing to step 4:
303 can be fit into 2295 7 times, resulting in a remainder of 174.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we subtract 2121 from 2295, we get 174.
Take the next digit (3) from the dividend and append it to 174, then repeat: 1743 / 303

Let's proceed to step 5:
1743 divided by 303 is 5 with a remainder of 228.
Record the quotient 5 as the next digit in the result. 
Result so far: 175.0
Subtracting 1515 from 1743 leaves us with 228.
Fetch the next digit (5) from the dividend, attach it to 228 and continue: 2285 / 303

Going ahead to step 6:
If we divide 2285 by 303, we get 7 and a remainder of 164.
The next digit of our result is 7. 
Result so far: 1757.0
The remainder is 164 after subtracting 2121 from 2285.
Include the next digit (7) from the dividend after 164, then repeat: 1647 / 303

On to step 7:
1647 divided by 303 is 5 with a remainder of 132.
Use 5 as the next digit of our solution. 
Result so far: 17575.0
If we take 1515 away from 1647, we end up with 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 303

Step 8:
The number 303 fits into 1323 4 times, leaving a remainder of 111.
Use 4 as the next digit of our solution. 
Result so far: 175754.0
Deduct 1212 from 1323 and we're left with 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 9:
303 goes into 1110 3 times with a remainder of 201.
Record the quotient 3 as the next digit in the result. 
Result so far: 175754.3
If we subtract 909 from 1110, we get 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Advancing to step 10:
2010 divided by 303 is 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 175754.36
Subtracting 1818 from 2010 leaves us with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
When dividing 1920 by 303, we get 6 with a remainder of 102.
Record the quotient 6 as the next digit in the result. 
Result so far: 175754.366
If we take 1818 away from 1920, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Our division results in 175754.366 with a remaining 0.0102.
