We look at the division of 48249387 by 228 
The aim is to understand the frequency of 228 in 48249387.

Step 1:
228 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 228

Advancing to step 2:
228 goes into 48 0 times with a remainder of 48.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 228

Advancing to step 3:
When dividing 482 by 228, we get 2 with a remainder of 26.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 26 after subtracting 456 from 482.
Fetch the next digit (4) from the dividend, attach it to 26 and continue: 264 / 228

Advancing to step 4:
If we divide 264 by 228, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 228 from 264, we get 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 228

Step 5:
369 divided by 228 is 1 with a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 211.0
Subtracting 228 from 369 leaves us with 141.
Append the next digit (3) from the dividend to 141 and continue with: 1413 / 228

Advancing to step 6:
228 goes into 1413 6 times with a remainder of 45.
Record the quotient 6 as the next digit in the result. 
Result so far: 2116.0
Deduct 1368 from 1413 and we're left with 45.
Append the next digit (8) from the dividend to 45 and continue with: 458 / 228

Going ahead to step 7:
228 goes into 458 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 21162.0
Subtracting 456 from 458 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 228

Going ahead to step 8:
When dividing 27 by 228, we get 0 with a remainder of 27.
The next digit of our result is 0. 
Result so far: 211620.0
If we subtract 0 from 27, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
228 goes into 270 1 times with a remainder of 42.
The next digit of our result is 1. 
Result so far: 211620.1
If we take 228 away from 270, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
If we divide 420 by 228, we get 1 and a remainder of 192.
Put 1 as the next digit of the answer. 
Result so far: 211620.11
If we subtract 228 from 420, 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.

After the division, we end up with 211620.11 and a remainder of 0.192.
