28498121 divided by 124 
The aim is to understand the frequency of 124 in 28498121.

Advancing to step 1:
The number 124 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 124

Let's proceed to step 2:
When dividing 28 by 124, we get 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 124

Moving on to step 3:
The number 124 fits into 284 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 248 away from 284, we end up with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 124

Going ahead to step 4:
124 goes into 369 2 times with a remainder of 121.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 248 from 369 and we're left with 121.
Take the next digit (8) from the dividend and append it to 121, then repeat: 1218 / 124

Going ahead to step 5:
The number 124 fits into 1218 9 times, leaving a remainder of 102.
Put 9 as the next digit of the answer. 
Result so far: 229.0
The remainder is 102 after subtracting 1116 from 1218.
Grab the next digit (1) from the dividend, add it to 102, then carry on: 1021 / 124

Let's proceed to step 6:
The number 124 fits into 1021 8 times, leaving a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 2298.0
If we take 992 away from 1021, we end up with 29.
Bring next digit (2) of the dividend behind the 29 and repeat the process: 292 / 124

Step 7:
124 goes into 292 2 times with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 22982.0
The remainder is 44 after subtracting 248 from 292.
Bring next digit (1) of the dividend behind the 44 and repeat the process: 441 / 124

On to step 8:
441 divided by 124 is 3 with a remainder of 69.
The next digit of our result is 3. 
Result so far: 229823.0
Deduct 372 from 441 and we're left with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 9:
The number 124 fits into 690 5 times, leaving a remainder of 70.
The next digit of our result is 5. 
Result so far: 229823.5
Subtracting 620 from 690 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 10:
If we divide 700 by 124, we get 5 and a remainder of 80.
Put 5 as the next digit of the answer. 
Result so far: 229823.55
Subtract 620 from 700 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 229823.55 with a remaining 0.08.
