9548539 ÷ 228 
The aim is to understand the frequency of 228 in 9548539.

On to step 1:
The number 228 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 228

On to step 2:
When dividing 95 by 228, we get 0 with a remainder of 95.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 95 to get 95.
Bring next digit (4) of the dividend behind the 95 and repeat the process: 954 / 228

Advancing to step 3:
When dividing 954 by 228, we get 4 with a remainder of 42.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 912 from 954, we get 42.
Take the next digit (8) from the dividend and append it to 42, then repeat: 428 / 228

Going ahead to step 4:
428 divided by 228 is 1 with a remainder of 200.
Put 1 as the next digit of the answer. 
Result so far: 41.0
Deduct 228 from 428 and we're left with 200.
Include the next digit (5) from the dividend after 200, then repeat: 2005 / 228

Step 5:
When dividing 2005 by 228, we get 8 with a remainder of 181.
Put 8 as the next digit of the answer. 
Result so far: 418.0
The remainder is 181 after subtracting 1824 from 2005.
Append the next digit (3) from the dividend to 181 and continue with: 1813 / 228

Let's proceed to step 6:
If we divide 1813 by 228, we get 7 and a remainder of 217.
The number 7 becomes the next digit in our result. 
Result so far: 4187.0
If we subtract 1596 from 1813, we get 217.
Take the next digit (9) from the dividend and append it to 217, then repeat: 2179 / 228

Advancing to step 7:
228 can be fit into 2179 9 times, resulting in a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 41879.0
If we subtract 2052 from 2179, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 8:
The number 228 fits into 1270 5 times, leaving a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 41879.5
Subtract 1140 from 1270 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
228 goes into 1300 5 times with a remainder of 160.
Use 5 as the next digit of our solution. 
Result so far: 41879.55
Deduct 1140 from 1300 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 41879.55 with a remainder of 0.16.
