12074894 divided by 245 
The aim is to understand the frequency of 245 in 12074894.

Advancing to step 1:
245 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 245

Going ahead to step 2:
When dividing 12 by 245, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 245

Step 3:
The number 245 fits into 120 0 times, leaving a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 120 and we're left with 120.
Grab the next digit (7) from the dividend, add it to 120, then carry on: 1207 / 245

On to step 4:
1207 divided by 245 is 4 with a remainder of 227.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 227 after subtracting 980 from 1207.
Bring next digit (4) of the dividend behind the 227 and repeat the process: 2274 / 245

Advancing to step 5:
When dividing 2274 by 245, we get 9 with a remainder of 69.
The next digit of our result is 9. 
Result so far: 49.0
Subtracting 2205 from 2274 leaves us with 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 245

Let's proceed to step 6:
245 goes into 698 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 492.0
If we take 490 away from 698, we end up with 208.
Take the next digit (9) from the dividend and append it to 208, then repeat: 2089 / 245

Going ahead to step 7:
If we divide 2089 by 245, we get 8 and a remainder of 129.
Use 8 as the next digit of our solution. 
Result so far: 4928.0
The remainder is 129 after subtracting 1960 from 2089.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 245

Moving on to step 8:
1294 divided by 245 is 5 with a remainder of 69.
Use 5 as the next digit of our solution. 
Result so far: 49285.0
Subtract 1225 from 1294 to get 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:
If we divide 690 by 245, we get 2 and a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 49285.2
The remainder is 200 after subtracting 490 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
The number 245 fits into 2000 8 times, leaving a remainder of 40.
The number 8 becomes the next digit in our result. 
Result so far: 49285.28
Subtract 1960 from 2000 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
245 can be fit into 400 1 times, resulting in a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 49285.281
The remainder is 155 after subtracting 245 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Going ahead to step 12:
If we divide 1550 by 245, we get 6 and a remainder of 80.
Put 6 as the next digit of the answer. 
Result so far: 49285.2816
Deduct 1470 from 1550 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
When dividing 800 by 245, we get 3 with a remainder of 65.
The next digit of our result is 3. 
Result so far: 49285.28163
Subtracting 735 from 800 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 14:
When dividing 650 by 245, we get 2 with a remainder of 160.
Record the quotient 2 as the next digit in the result. 
Result so far: 49285.281632
Subtract 490 from 650 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 15:
If we divide 1600 by 245, we get 6 and a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 49285.2816326
Deduct 1470 from 1600 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 16:
When dividing 1300 by 245, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 49285.28163265
The remainder is 75 after subtracting 1225 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The final result is 49285.28163265 with a remainder of 7.5e-08.
