We look at the division of 36548251 by 525 
The aim is to understand the frequency of 525 in 36548251.

Moving on to step 1:
When dividing 3 by 525, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 525

On to step 2:
525 goes into 36 0 times with a remainder of 36.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 525

On to step 3:
The number 525 fits into 365 0 times, leaving a remainder of 365.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 365, we end up with 365.
Bring next digit (4) of the dividend behind the 365 and repeat the process: 3654 / 525

On to step 4:
The number 525 fits into 3654 6 times, leaving a remainder of 504.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 3150 away from 3654, we end up with 504.
Fetch the next digit (8) from the dividend, attach it to 504 and continue: 5048 / 525

Let's proceed to step 5:
5048 divided by 525 is 9 with a remainder of 323.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
The remainder is 323 after subtracting 4725 from 5048.
Fetch the next digit (2) from the dividend, attach it to 323 and continue: 3232 / 525

Let's proceed to step 6:
When dividing 3232 by 525, we get 6 with a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 696.0
Deduct 3150 from 3232 and we're left with 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 525

On to step 7:
When dividing 825 by 525, we get 1 with a remainder of 300.
The next digit of our result is 1. 
Result so far: 6961.0
Subtracting 525 from 825 leaves us with 300.
Include the next digit (1) from the dividend after 300, then repeat: 3001 / 525

On to step 8:
3001 divided by 525 is 5 with a remainder of 376.
Write down 5 as next digit of the result. 
Result so far: 69615.0
Subtracting 2625 from 3001 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 9:
The number 525 fits into 3760 7 times, leaving a remainder of 85.
The next digit of our result is 7. 
Result so far: 69615.7
Subtracting 3675 from 3760 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 10:
The number 525 fits into 850 1 times, leaving a remainder of 325.
The next digit of our result is 1. 
Result so far: 69615.71
If we take 525 away from 850, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

On to step 11:
If we divide 3250 by 525, we get 6 and a remainder of 100.
The next digit of our result is 6. 
Result so far: 69615.716
Subtracting 3150 from 3250 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
525 can be fit into 1000 1 times, resulting in a remainder of 475.
Use 1 as the next digit of our solution. 
Result so far: 69615.7161
If we subtract 525 from 1000, we get 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 13:
525 goes into 4750 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 69615.71619
Subtract 4725 from 4750 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 14:
When dividing 250 by 525, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 69615.71619
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 15:
The number 525 fits into 2500 4 times, leaving a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 69615.7161904
Subtracting 2100 from 2500 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 16:
4000 divided by 525 is 7 with a remainder of 325.
The next digit of our result is 7. 
Result so far: 69615.71619047
Subtract 3675 from 4000 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 69615.71619047 and a remainder of 3.25e-07.
