We're dividing 12249373 by 245 
The aim is to understand the frequency of 245 in 12249373.

Going ahead to step 1:
The number 245 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 245

On to step 2:
When dividing 12 by 245, we get 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 245

Advancing to step 3:
245 can be fit into 122 0 times, resulting in a remainder of 122.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Take the next digit (4) from the dividend and append it to 122, then repeat: 1224 / 245

On to step 4:
If we divide 1224 by 245, we get 4 and a remainder of 244.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 980 from 1224 leaves us with 244.
Grab the next digit (9) from the dividend, add it to 244, then carry on: 2449 / 245

Moving on to step 5:
245 can be fit into 2449 9 times, resulting in a remainder of 244.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 2205 from 2449 leaves us with 244.
Take the next digit (3) from the dividend and append it to 244, then repeat: 2443 / 245

On to step 6:
2443 divided by 245 is 9 with a remainder of 238.
The next digit of our result is 9. 
Result so far: 499.0
If we subtract 2205 from 2443, we get 238.
Include the next digit (7) from the dividend after 238, then repeat: 2387 / 245

Let's proceed to step 7:
When dividing 2387 by 245, we get 9 with a remainder of 182.
Write down 9 as next digit of the result. 
Result so far: 4999.0
Subtracting 2205 from 2387 leaves us with 182.
Grab the next digit (3) from the dividend, add it to 182, then carry on: 1823 / 245

On to step 8:
The number 245 fits into 1823 7 times, leaving a remainder of 108.
Use 7 as the next digit of our solution. 
Result so far: 49997.0
Deduct 1715 from 1823 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 9:
1080 divided by 245 is 4 with a remainder of 100.
The next digit of our result is 4. 
Result so far: 49997.4
If we subtract 980 from 1080, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 10:
245 can be fit into 1000 4 times, resulting in a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 49997.44
The remainder is 20 after subtracting 980 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 49997.44 and a remainder of 0.02.
