We look at the division of 78132772 by 303 
The aim is to understand the frequency of 303 in 78132772.

Let's proceed to step 1:
The number 303 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 303

Going ahead to step 2:
78 divided by 303 is 0 with a remainder of 78.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (1) of the dividend behind the 78 and repeat the process: 781 / 303

Let's proceed to step 3:
781 divided by 303 is 2 with a remainder of 175.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 175 after subtracting 606 from 781.
Include the next digit (3) from the dividend after 175, then repeat: 1753 / 303

Let's proceed to step 4:
303 goes into 1753 5 times with a remainder of 238.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 1515 from 1753 to get 238.
Bring next digit (2) of the dividend behind the 238 and repeat the process: 2382 / 303

Let's proceed to step 5:
The number 303 fits into 2382 7 times, leaving a remainder of 261.
The next digit of our result is 7. 
Result so far: 257.0
The remainder is 261 after subtracting 2121 from 2382.
Bring next digit (7) of the dividend behind the 261 and repeat the process: 2617 / 303

Moving on to step 6:
303 can be fit into 2617 8 times, resulting in a remainder of 193.
Record the quotient 8 as the next digit in the result. 
Result so far: 2578.0
Subtracting 2424 from 2617 leaves us with 193.
Take the next digit (7) from the dividend and append it to 193, then repeat: 1937 / 303

On to step 7:
303 goes into 1937 6 times with a remainder of 119.
Write down 6 as next digit of the result. 
Result so far: 25786.0
Subtracting 1818 from 1937 leaves us with 119.
Grab the next digit (2) from the dividend, add it to 119, then carry on: 1192 / 303

Moving on to step 8:
1192 divided by 303 is 3 with a remainder of 283.
Record the quotient 3 as the next digit in the result. 
Result so far: 257863.0
Subtracting 909 from 1192 leaves us with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Moving on to step 9:
303 goes into 2830 9 times with a remainder of 103.
The next digit of our result is 9. 
Result so far: 257863.9
Deduct 2727 from 2830 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 10:
1030 divided by 303 is 3 with a remainder of 121.
Record the quotient 3 as the next digit in the result. 
Result so far: 257863.93
Subtract 909 from 1030 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 11:
The number 303 fits into 1210 3 times, leaving a remainder of 301.
Use 3 as the next digit of our solution. 
Result so far: 257863.933
Subtract 909 from 1210 to get 301.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3010, and continue the process.

The final result is 257863.933 with a remainder of 0.0301.
