We're dividing 52662327 by 525 
The aim is to understand the frequency of 525 in 52662327.

Advancing to step 1:
The number 525 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 525

Moving on to step 2:
525 can be fit into 52 0 times, resulting in a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 525

Going ahead to step 3:
When dividing 526 by 525, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 1 after subtracting 525 from 526.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 525

Let's proceed to step 4:
16 divided by 525 is 0 with a remainder of 16.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 16, we end up with 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 525

Step 5:
When dividing 162 by 525, we get 0 with a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
The remainder is 162 after subtracting 0 from 162.
Grab the next digit (3) from the dividend, add it to 162, then carry on: 1623 / 525

Going ahead to step 6:
The number 525 fits into 1623 3 times, leaving a remainder of 48.
Put 3 as the next digit of the answer. 
Result so far: 1003.0
Subtract 1575 from 1623 to get 48.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 525

Advancing to step 7:
When dividing 482 by 525, we get 0 with a remainder of 482.
Put 0 as the next digit of the answer. 
Result so far: 10030.0
The remainder is 482 after subtracting 0 from 482.
Take the next digit (7) from the dividend and append it to 482, then repeat: 4827 / 525

Step 8:
If we divide 4827 by 525, we get 9 and a remainder of 102.
Write down 9 as next digit of the result. 
Result so far: 100309.0
If we subtract 4725 from 4827, we get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Let's proceed to step 9:
The number 525 fits into 1020 1 times, leaving a remainder of 495.
Record the quotient 1 as the next digit in the result. 
Result so far: 100309.1
If we take 525 away from 1020, we end up with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

Moving on to step 10:
If we divide 4950 by 525, we get 9 and a remainder of 225.
The next digit of our result is 9. 
Result so far: 100309.19
Deduct 4725 from 4950 and we're left with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 11:
The number 525 fits into 2250 4 times, leaving a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 100309.194
The remainder is 150 after subtracting 2100 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 12:
When dividing 1500 by 525, we get 2 with a remainder of 450.
Record the quotient 2 as the next digit in the result. 
Result so far: 100309.1942
Deduct 1050 from 1500 and we're left with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Going ahead to step 13:
525 can be fit into 4500 8 times, resulting in a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 100309.19428
If we take 4200 away from 4500, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

On to step 14:
The number 525 fits into 3000 5 times, leaving a remainder of 375.
The next digit of our result is 5. 
Result so far: 100309.194285
Subtract 2625 from 3000 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 15:
3750 divided by 525 is 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 100309.1942857
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.

On to step 16:
If we divide 750 by 525, we get 1 and a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 100309.19428571
If we subtract 525 from 750, we get 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

The final outcome is 100309.19428571, with a leftover of 2.25e-07.
