Let's divide 968718 by 525
The aim is to understand the frequency of 525 in 968718.

On to step 1:
The number 525 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 525

Step 2:
If we divide 96 by 525, we get 0 and a remainder of 96.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 96 leaves us with 96.
Take the next digit (8) from the dividend and append it to 96, then repeat: 968 / 525

Step 3:
The number 525 fits into 968 1 times, leaving a remainder of 443.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 525 from 968 to get 443.
Append the next digit (7) from the dividend to 443 and continue with: 4437 / 525

Going ahead to step 4:
4437 divided by 525 is 8 with a remainder of 237.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 4200 from 4437, we get 237.
Append the next digit (1) from the dividend to 237 and continue with: 2371 / 525

On to step 5:
If we divide 2371 by 525, we get 4 and a remainder of 271.
The number 4 becomes the next digit in our result. 
Result so far: 184.0
If we subtract 2100 from 2371, we get 271.
Fetch the next digit (8) from the dividend, attach it to 271 and continue: 2718 / 525

On to step 6:
If we divide 2718 by 525, we get 5 and a remainder of 93.
Use 5 as the next digit of our solution. 
Result so far: 1845.0
If we take 2625 away from 2718, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 7:
930 divided by 525 is 1 with a remainder of 405.
The next digit of our result is 1. 
Result so far: 1845.1
Subtracting 525 from 930 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 8:
525 can be fit into 4050 7 times, resulting in a remainder of 375.
Record the quotient 7 as the next digit in the result. 
Result so far: 1845.17
If we subtract 3675 from 4050, we 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 9:
The number 525 fits into 3750 7 times, leaving a remainder of 75.
Record the quotient 7 as the next digit in the result. 
Result so far: 1845.177
Deduct 3675 from 3750 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 1845.177 and a remainder of 0.0075.
