66645248 ÷ 245 
The aim is to understand the frequency of 245 in 66645248.

Going ahead to step 1:
245 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 245

Advancing to step 2:
If we divide 66 by 245, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 245

Let's proceed to step 3:
If we divide 666 by 245, we get 2 and a remainder of 176.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 490 from 666 to get 176.
Include the next digit (4) from the dividend after 176, then repeat: 1764 / 245

Step 4:
245 can be fit into 1764 7 times, resulting in a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
Subtracting 1715 from 1764 leaves us with 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 245

Let's proceed to step 5:
The number 245 fits into 495 2 times, leaving a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 272.0
If we take 490 away from 495, we end up with 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 245

Advancing to step 6:
When dividing 52 by 245, we get 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 2720.0
Subtract 0 from 52 to get 52.
Grab the next digit (4) from the dividend, add it to 52, then carry on: 524 / 245

Advancing to step 7:
245 can be fit into 524 2 times, resulting in a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 27202.0
Subtracting 490 from 524 leaves us with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 245

Let's proceed to step 8:
348 divided by 245 is 1 with a remainder of 103.
Write down 1 as next digit of the result. 
Result so far: 272021.0
Deduct 245 from 348 and we're left with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Going ahead to step 9:
245 can be fit into 1030 4 times, resulting in a remainder of 50.
Write down 4 as next digit of the result. 
Result so far: 272021.4
Subtract 980 from 1030 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
The number 245 fits into 500 2 times, leaving a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 272021.42
If we subtract 490 from 500, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
100 divided by 245 is 0 with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 272021.42
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 12:
245 goes into 1000 4 times with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 272021.4204
Deduct 980 from 1000 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
The number 245 fits into 200 0 times, leaving a remainder of 200.
Use 0 as the next digit of our solution. 
Result so far: 272021.4204
Subtract 0 from 200 to get 200.
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 14:
245 goes into 2000 8 times with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 272021.420408
The remainder is 40 after subtracting 1960 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 15:
245 goes into 400 1 times with a remainder of 155.
The number 1 becomes the next digit in our result. 
Result so far: 272021.4204081
Subtracting 245 from 400 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 16:
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: 272021.42040816
The remainder is 80 after subtracting 1470 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 272021.42040816 with a remainder of 8e-08.
