Let's divide 9753755 by 665
The aim is to understand the frequency of 665 in 9753755.

Advancing to step 1:
9 divided by 665 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 665

Step 2:
When dividing 97 by 665, we get 0 with a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Append the next digit (5) from the dividend to 97 and continue with: 975 / 665

On to step 3:
If we divide 975 by 665, we get 1 and a remainder of 310.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 665 from 975 to get 310.
Grab the next digit (3) from the dividend, add it to 310, then carry on: 3103 / 665

Step 4:
The number 665 fits into 3103 4 times, leaving a remainder of 443.
Use 4 as the next digit of our solution. 
Result so far: 14.0
If we subtract 2660 from 3103, we get 443.
Append the next digit (7) from the dividend to 443 and continue with: 4437 / 665

Moving on to step 5:
665 goes into 4437 6 times with a remainder of 447.
Write down 6 as next digit of the result. 
Result so far: 146.0
Subtracting 3990 from 4437 leaves us with 447.
Include the next digit (5) from the dividend after 447, then repeat: 4475 / 665

Moving on to step 6:
If we divide 4475 by 665, we get 6 and a remainder of 485.
Put 6 as the next digit of the answer. 
Result so far: 1466.0
Deduct 3990 from 4475 and we're left with 485.
Bring next digit (5) of the dividend behind the 485 and repeat the process: 4855 / 665

Let's proceed to step 7:
When dividing 4855 by 665, we get 7 with a remainder of 200.
The number 7 becomes the next digit in our result. 
Result so far: 14667.0
Subtracting 4655 from 4855 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 8:
The number 665 fits into 2000 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 14667.3
Subtract 1995 from 2000 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 665, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 14667.3
Subtract 0 from 50 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.

On to step 10:
If we divide 500 by 665, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 14667.3
Deduct 0 from 500 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

After the division, we end up with 14667.3 and a remainder of 0.05.
