72755901 ÷ 228 
The aim is to understand the frequency of 228 in 72755901.

On to step 1:
The number 228 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 228

On to step 2:
72 divided by 228 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 72, we get 72.
Take the next digit (7) from the dividend and append it to 72, then repeat: 727 / 228

Going ahead to step 3:
727 divided by 228 is 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 684 away from 727, we end up with 43.
Bring next digit (5) of the dividend behind the 43 and repeat the process: 435 / 228

Advancing to step 4:
The number 228 fits into 435 1 times, leaving a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 228 away from 435, we end up with 207.
Take the next digit (5) from the dividend and append it to 207, then repeat: 2075 / 228

Going ahead to step 5:
2075 divided by 228 is 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 319.0
Subtracting 2052 from 2075 leaves us with 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 228

On to step 6:
228 goes into 239 1 times with a remainder of 11.
The next digit of our result is 1. 
Result so far: 3191.0
Subtracting 228 from 239 leaves us with 11.
Take the next digit (0) from the dividend and append it to 11, then repeat: 110 / 228

Advancing to step 7:
When dividing 110 by 228, we get 0 with a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 31910.0
The remainder is 110 after subtracting 0 from 110.
Grab the next digit (1) from the dividend, add it to 110, then carry on: 1101 / 228

Step 8:
When dividing 1101 by 228, we get 4 with a remainder of 189.
Record the quotient 4 as the next digit in the result. 
Result so far: 319104.0
If we subtract 912 from 1101, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Let's proceed to step 9:
The number 228 fits into 1890 8 times, leaving a remainder of 66.
Record the quotient 8 as the next digit in the result. 
Result so far: 319104.8
Subtracting 1824 from 1890 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
The number 228 fits into 660 2 times, leaving a remainder of 204.
Put 2 as the next digit of the answer. 
Result so far: 319104.82
The remainder is 204 after subtracting 456 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Moving on to step 11:
228 goes into 2040 8 times with a remainder of 216.
Record the quotient 8 as the next digit in the result. 
Result so far: 319104.828
The remainder is 216 after subtracting 1824 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 12:
The number 228 fits into 2160 9 times, leaving a remainder of 108.
Write down 9 as next digit of the result. 
Result so far: 319104.8289
If we take 2052 away from 2160, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
If we divide 1080 by 228, we get 4 and a remainder of 168.
The number 4 becomes the next digit in our result. 
Result so far: 319104.82894
Deduct 912 from 1080 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
If we divide 1680 by 228, we get 7 and a remainder of 84.
Put 7 as the next digit of the answer. 
Result so far: 319104.828947
Subtract 1596 from 1680 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 15:
When dividing 840 by 228, we get 3 with a remainder of 156.
Record the quotient 3 as the next digit in the result. 
Result so far: 319104.8289473
The remainder is 156 after subtracting 684 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Let's proceed to step 16:
When dividing 1560 by 228, we get 6 with a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 319104.82894736
If we subtract 1368 from 1560, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

The quotient of the division is 319104.82894736, and the remainder is 1.92e-07.
