65020205 ÷ 685 
The aim is to understand the frequency of 685 in 65020205.

Going ahead to step 1:
The number 685 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 685

Advancing to step 2:
65 divided by 685 is 0 with a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 685

Moving on to step 3:
650 divided by 685 is 0 with a remainder of 650.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 650, we get 650.
Append the next digit (2) from the dividend to 650 and continue with: 6502 / 685

Step 4:
If we divide 6502 by 685, we get 9 and a remainder of 337.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 6165 from 6502, we get 337.
Append the next digit (0) from the dividend to 337 and continue with: 3370 / 685

Step 5:
685 can be fit into 3370 4 times, resulting in a remainder of 630.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 630 after subtracting 2740 from 3370.
Grab the next digit (2) from the dividend, add it to 630, then carry on: 6302 / 685

On to step 6:
685 can be fit into 6302 9 times, resulting in a remainder of 137.
The number 9 becomes the next digit in our result. 
Result so far: 949.0
If we subtract 6165 from 6302, we get 137.
Append the next digit (0) from the dividend to 137 and continue with: 1370 / 685

Step 7:
When dividing 1370 by 685, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 9492.0
Subtracting 1370 from 1370 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 685

Step 8:
5 divided by 685 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 94920.0
If we subtract 0 from 5, we 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.

Advancing to step 9:
When dividing 50 by 685, we get 0 with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 94920.0
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.

Step 10:
500 divided by 685 is 0 with a remainder of 500.
Write down 0 as next digit of the result. 
Result so far: 94920.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final result is 94920.0 with a remainder of 0.5.
