We look at the division of 53414406 by 303 
The aim is to understand the frequency of 303 in 53414406.

Step 1:
When dividing 5 by 303, we get 0 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.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 303

On to step 2:
53 divided by 303 is 0 with a remainder of 53.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 53, we get 53.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 303

Let's proceed to step 3:
When dividing 534 by 303, we get 1 with a remainder of 231.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 303 from 534, we get 231.
Include the next digit (1) from the dividend after 231, then repeat: 2311 / 303

Going ahead to step 4:
303 can be fit into 2311 7 times, resulting in a remainder of 190.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 2121 from 2311, we get 190.
Append the next digit (4) from the dividend to 190 and continue with: 1904 / 303

Step 5:
The number 303 fits into 1904 6 times, leaving a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
The remainder is 86 after subtracting 1818 from 1904.
Take the next digit (4) from the dividend and append it to 86, then repeat: 864 / 303

Advancing to step 6:
303 can be fit into 864 2 times, resulting in a remainder of 258.
Put 2 as the next digit of the answer. 
Result so far: 1762.0
If we take 606 away from 864, we end up with 258.
Bring next digit (0) of the dividend behind the 258 and repeat the process: 2580 / 303

Moving on to step 7:
303 goes into 2580 8 times with a remainder of 156.
Write down 8 as next digit of the result. 
Result so far: 17628.0
Subtract 2424 from 2580 to get 156.
Fetch the next digit (6) from the dividend, attach it to 156 and continue: 1566 / 303

Moving on to step 8:
The number 303 fits into 1566 5 times, leaving a remainder of 51.
Use 5 as the next digit of our solution. 
Result so far: 176285.0
Deduct 1515 from 1566 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 9:
When dividing 510 by 303, we get 1 with a remainder of 207.
The number 1 becomes the next digit in our result. 
Result so far: 176285.1
If we take 303 away from 510, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Moving on to step 10:
When dividing 2070 by 303, we get 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 176285.16
Subtracting 1818 from 2070 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 11:
The number 303 fits into 2520 8 times, leaving a remainder of 96.
Record the quotient 8 as the next digit in the result. 
Result so far: 176285.168
Subtracting 2424 from 2520 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Step 12:
303 can be fit into 960 3 times, resulting in a remainder of 51.
The next digit of our result is 3. 
Result so far: 176285.1683
If we subtract 909 from 960, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 13:
The number 303 fits into 510 1 times, leaving a remainder of 207.
Write down 1 as next digit of the result. 
Result so far: 176285.16831
The remainder is 207 after subtracting 303 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

On to step 14:
If we divide 2070 by 303, we get 6 and a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 176285.168316
If we take 1818 away from 2070, we end up with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 15:
303 goes into 2520 8 times with a remainder of 96.
Put 8 as the next digit of the answer. 
Result so far: 176285.1683168
If we take 2424 away from 2520, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 16:
When dividing 960 by 303, we get 3 with a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 176285.16831683
If we take 909 away from 960, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 176285.16831683 with a remaining 5.1e-08.
