We look at the division of 65249574 by 685 
The aim is to understand the frequency of 685 in 65249574.

Let's proceed to step 1:
The number 685 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 685

Step 2:
65 divided by 685 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (2) from the dividend, add it to 65, then carry on: 652 / 685

On to step 3:
The number 685 fits into 652 0 times, leaving a remainder of 652.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 652, we end up with 652.
Bring next digit (4) of the dividend behind the 652 and repeat the process: 6524 / 685

Let's proceed to step 4:
When dividing 6524 by 685, we get 9 with a remainder of 359.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 6165 from 6524 leaves us with 359.
Take the next digit (9) from the dividend and append it to 359, then repeat: 3599 / 685

Advancing to step 5:
685 can be fit into 3599 5 times, resulting in a remainder of 174.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we subtract 3425 from 3599, we get 174.
Include the next digit (5) from the dividend after 174, then repeat: 1745 / 685

Going ahead to step 6:
685 can be fit into 1745 2 times, resulting in a remainder of 375.
Use 2 as the next digit of our solution. 
Result so far: 952.0
The remainder is 375 after subtracting 1370 from 1745.
Fetch the next digit (7) from the dividend, attach it to 375 and continue: 3757 / 685

Let's proceed to step 7:
If we divide 3757 by 685, we get 5 and a remainder of 332.
Put 5 as the next digit of the answer. 
Result so far: 9525.0
If we subtract 3425 from 3757, we get 332.
Take the next digit (4) from the dividend and append it to 332, then repeat: 3324 / 685

Step 8:
When dividing 3324 by 685, we get 4 with a remainder of 584.
The number 4 becomes the next digit in our result. 
Result so far: 95254.0
Subtracting 2740 from 3324 leaves us with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

Let's proceed to step 9:
5840 divided by 685 is 8 with a remainder of 360.
Put 8 as the next digit of the answer. 
Result so far: 95254.8
If we subtract 5480 from 5840, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 10:
If we divide 3600 by 685, we get 5 and a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 95254.85
Deduct 3425 from 3600 and we're left with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
When dividing 1750 by 685, we get 2 with a remainder of 380.
Record the quotient 2 as the next digit in the result. 
Result so far: 95254.852
Deduct 1370 from 1750 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Going ahead to step 12:
685 can be fit into 3800 5 times, resulting in a remainder of 375.
The next digit of our result is 5. 
Result so far: 95254.8525
Subtract 3425 from 3800 to get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

On to step 13:
If we divide 3750 by 685, we get 5 and a remainder of 325.
Use 5 as the next digit of our solution. 
Result so far: 95254.85255
Subtract 3425 from 3750 to get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

After the division, we end up with 95254.85255 and a remainder of 0.000325.
