We look at the division of 68537725 by 755 
The aim is to understand the frequency of 755 in 68537725.

Let's proceed to step 1:
If we divide 6 by 755, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 755

On to step 2:
The number 755 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Include the next digit (5) from the dividend after 68, then repeat: 685 / 755

On to step 3:
When dividing 685 by 755, we get 0 with a remainder of 685.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 685 leaves us with 685.
Bring next digit (3) of the dividend behind the 685 and repeat the process: 6853 / 755

Step 4:
6853 divided by 755 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 6795 away from 6853, we end up with 58.
Bring next digit (7) of the dividend behind the 58 and repeat the process: 587 / 755

Going ahead to step 5:
755 goes into 587 0 times with a remainder of 587.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we take 0 away from 587, we end up with 587.
Include the next digit (7) from the dividend after 587, then repeat: 5877 / 755

Step 6:
The number 755 fits into 5877 7 times, leaving a remainder of 592.
Use 7 as the next digit of our solution. 
Result so far: 907.0
If we subtract 5285 from 5877, we get 592.
Bring next digit (2) of the dividend behind the 592 and repeat the process: 5922 / 755

Step 7:
When dividing 5922 by 755, we get 7 with a remainder of 637.
The number 7 becomes the next digit in our result. 
Result so far: 9077.0
If we take 5285 away from 5922, we end up with 637.
Fetch the next digit (5) from the dividend, attach it to 637 and continue: 6375 / 755

Let's proceed to step 8:
The number 755 fits into 6375 8 times, leaving a remainder of 335.
Write down 8 as next digit of the result. 
Result so far: 90778.0
If we subtract 6040 from 6375, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Moving on to step 9:
If we divide 3350 by 755, we get 4 and a remainder of 330.
The number 4 becomes the next digit in our result. 
Result so far: 90778.4
If we subtract 3020 from 3350, we get 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

On to step 10:
When dividing 3300 by 755, we get 4 with a remainder of 280.
Use 4 as the next digit of our solution. 
Result so far: 90778.44
The remainder is 280 after subtracting 3020 from 3300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final result is 90778.44 with a remainder of 0.28.
