We look at the division of 1142905 by 249 
The aim is to understand the frequency of 249 in 1142905.

Step 1:
249 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 249

Going ahead to step 2:
The number 249 fits into 11 0 times, leaving a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 249

Step 3:
114 divided by 249 is 0 with a remainder of 114.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 114 to get 114.
Fetch the next digit (2) from the dividend, attach it to 114 and continue: 1142 / 249

Moving on to step 4:
249 goes into 1142 4 times with a remainder of 146.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 996 away from 1142, we end up with 146.
Bring next digit (9) of the dividend behind the 146 and repeat the process: 1469 / 249

On to step 5:
1469 divided by 249 is 5 with a remainder of 224.
The next digit of our result is 5. 
Result so far: 45.0
If we take 1245 away from 1469, we end up with 224.
Fetch the next digit (0) from the dividend, attach it to 224 and continue: 2240 / 249

Advancing to step 6:
249 can be fit into 2240 8 times, resulting in a remainder of 248.
Record the quotient 8 as the next digit in the result. 
Result so far: 458.0
If we take 1992 away from 2240, we end up with 248.
Bring next digit (5) of the dividend behind the 248 and repeat the process: 2485 / 249

Advancing to step 7:
249 goes into 2485 9 times with a remainder of 244.
The next digit of our result is 9. 
Result so far: 4589.0
If we take 2241 away from 2485, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Advancing to step 8:
The number 249 fits into 2440 9 times, leaving a remainder of 199.
The next digit of our result is 9. 
Result so far: 4589.9
Subtract 2241 from 2440 to get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 9:
When dividing 1990 by 249, we get 7 with a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 4589.97
The remainder is 247 after subtracting 1743 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Moving on to step 10:
249 can be fit into 2470 9 times, resulting in a remainder of 229.
Put 9 as the next digit of the answer. 
Result so far: 4589.979
The remainder is 229 after subtracting 2241 from 2470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2290, and continue the process.

Let's proceed to step 11:
249 can be fit into 2290 9 times, resulting in a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 4589.9799
If we subtract 2241 from 2290, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Our division results in 4589.9799 with a remaining 0.00049.
