We divide 54230909 by 303
The aim is to understand the frequency of 303 in 54230909.

On to step 1:
5 divided by 303 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 303

Step 2:
If we divide 54 by 303, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Bring next digit (2) of the dividend behind the 54 and repeat the process: 542 / 303

Moving on to step 3:
303 goes into 542 1 times with a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 303 from 542, we get 239.
Append the next digit (3) from the dividend to 239 and continue with: 2393 / 303

On to step 4:
2393 divided by 303 is 7 with a remainder of 272.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 2121 from 2393 and we're left with 272.
Take the next digit (0) from the dividend and append it to 272, then repeat: 2720 / 303

Let's proceed to step 5:
303 goes into 2720 8 times with a remainder of 296.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
If we subtract 2424 from 2720, we get 296.
Grab the next digit (9) from the dividend, add it to 296, then carry on: 2969 / 303

Advancing to step 6:
If we divide 2969 by 303, we get 9 and a remainder of 242.
Record the quotient 9 as the next digit in the result. 
Result so far: 1789.0
Deduct 2727 from 2969 and we're left with 242.
Bring next digit (0) of the dividend behind the 242 and repeat the process: 2420 / 303

On to step 7:
The number 303 fits into 2420 7 times, leaving a remainder of 299.
The next digit of our result is 7. 
Result so far: 17897.0
Deduct 2121 from 2420 and we're left with 299.
Include the next digit (9) from the dividend after 299, then repeat: 2999 / 303

Step 8:
303 can be fit into 2999 9 times, resulting in a remainder of 272.
Use 9 as the next digit of our solution. 
Result so far: 178979.0
The remainder is 272 after subtracting 2727 from 2999.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

On to step 9:
If we divide 2720 by 303, we get 8 and a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 178979.8
If we subtract 2424 from 2720, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 10:
303 goes into 2960 9 times with a remainder of 233.
Record the quotient 9 as the next digit in the result. 
Result so far: 178979.89
Subtracting 2727 from 2960 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Let's proceed to step 11:
If we divide 2330 by 303, we get 7 and a remainder of 209.
Use 7 as the next digit of our solution. 
Result so far: 178979.897
The remainder is 209 after subtracting 2121 from 2330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 12:
303 goes into 2090 6 times with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 178979.8976
Subtracting 1818 from 2090 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 13:
When dividing 2720 by 303, we get 8 with a remainder of 296.
The number 8 becomes the next digit in our result. 
Result so far: 178979.89768
If we subtract 2424 from 2720, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 14:
The number 303 fits into 2960 9 times, leaving a remainder of 233.
Use 9 as the next digit of our solution. 
Result so far: 178979.897689
Deduct 2727 from 2960 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Moving on to step 15:
The number 303 fits into 2330 7 times, leaving a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 178979.8976897
Subtract 2121 from 2330 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Moving on to step 16:
2090 divided by 303 is 6 with a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 178979.89768976
Subtract 1818 from 2090 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The final result is 178979.89768976 with a remainder of 2.72e-07.
