We look at the division of 28202846 by 249 
The aim is to understand the frequency of 249 in 28202846.

On to step 1:
If we divide 2 by 249, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 249

Step 2:
249 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 249

Advancing to step 3:
249 goes into 282 1 times with a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 249 from 282 to get 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 249

Advancing to step 4:
The number 249 fits into 330 1 times, leaving a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 249 from 330, we get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 249

Going ahead to step 5:
If we divide 812 by 249, we get 3 and a remainder of 65.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 747 from 812, we get 65.
Fetch the next digit (8) from the dividend, attach it to 65 and continue: 658 / 249

Step 6:
When dividing 658 by 249, we get 2 with a remainder of 160.
Use 2 as the next digit of our solution. 
Result so far: 1132.0
Deduct 498 from 658 and we're left with 160.
Take the next digit (4) from the dividend and append it to 160, then repeat: 1604 / 249

On to step 7:
1604 divided by 249 is 6 with a remainder of 110.
The next digit of our result is 6. 
Result so far: 11326.0
Subtract 1494 from 1604 to get 110.
Take the next digit (6) from the dividend and append it to 110, then repeat: 1106 / 249

Going ahead to step 8:
249 can be fit into 1106 4 times, resulting in a remainder of 110.
Put 4 as the next digit of the answer. 
Result so far: 113264.0
If we subtract 996 from 1106, we get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 9:
249 can be fit into 1100 4 times, resulting in a remainder of 104.
The next digit of our result is 4. 
Result so far: 113264.4
Subtracting 996 from 1100 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 10:
When dividing 1040 by 249, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 113264.44
If we subtract 996 from 1040, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 113264.44, and the remainder is 0.044.
