We look at the division of 30657686 by 245 
The aim is to understand the frequency of 245 in 30657686.

Advancing to step 1:
When dividing 3 by 245, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 245

Advancing to step 2:
The number 245 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 245

Moving on to step 3:
If we divide 306 by 245, we get 1 and a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 61 after subtracting 245 from 306.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 245

Advancing to step 4:
615 divided by 245 is 2 with a remainder of 125.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we subtract 490 from 615, we get 125.
Include the next digit (7) from the dividend after 125, then repeat: 1257 / 245

Advancing to step 5:
If we divide 1257 by 245, we get 5 and a remainder of 32.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtract 1225 from 1257 to get 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 245

Step 6:
245 goes into 326 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 1251.0
The remainder is 81 after subtracting 245 from 326.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 245

Going ahead to step 7:
818 divided by 245 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 12513.0
Subtracting 735 from 818 leaves us with 83.
Include the next digit (6) from the dividend after 83, then repeat: 836 / 245

Let's proceed to step 8:
If we divide 836 by 245, we get 3 and a remainder of 101.
The next digit of our result is 3. 
Result so far: 125133.0
Subtracting 735 from 836 leaves us with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 9:
The number 245 fits into 1010 4 times, leaving a remainder of 30.
The number 4 becomes the next digit in our result. 
Result so far: 125133.4
If we take 980 away from 1010, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 245 fits into 300 1 times, leaving a remainder of 55.
Use 1 as the next digit of our solution. 
Result so far: 125133.41
The remainder is 55 after subtracting 245 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 11:
If we divide 550 by 245, we get 2 and a remainder of 60.
Use 2 as the next digit of our solution. 
Result so far: 125133.412
Subtracting 490 from 550 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 12:
245 goes into 600 2 times with a remainder of 110.
Write down 2 as next digit of the result. 
Result so far: 125133.4122
The remainder is 110 after subtracting 490 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The quotient of the division is 125133.4122, and the remainder is 0.0011.
