7729395 divided by 525 
The aim is to understand the frequency of 525 in 7729395.

Advancing to step 1:
525 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 525

Advancing to step 2:
The number 525 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Take the next digit (2) from the dividend and append it to 77, then repeat: 772 / 525

Step 3:
525 can be fit into 772 1 times, resulting in a remainder of 247.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 525 from 772 to get 247.
Grab the next digit (9) from the dividend, add it to 247, then carry on: 2479 / 525

Moving on to step 4:
When dividing 2479 by 525, we get 4 with a remainder of 379.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 2100 from 2479, we get 379.
Include the next digit (3) from the dividend after 379, then repeat: 3793 / 525

Going ahead to step 5:
If we divide 3793 by 525, we get 7 and a remainder of 118.
Write down 7 as next digit of the result. 
Result so far: 147.0
Subtracting 3675 from 3793 leaves us with 118.
Take the next digit (9) from the dividend and append it to 118, then repeat: 1189 / 525

Moving on to step 6:
If we divide 1189 by 525, we get 2 and a remainder of 139.
Use 2 as the next digit of our solution. 
Result so far: 1472.0
Subtract 1050 from 1189 to get 139.
Fetch the next digit (5) from the dividend, attach it to 139 and continue: 1395 / 525

Advancing to step 7:
525 can be fit into 1395 2 times, resulting in a remainder of 345.
The next digit of our result is 2. 
Result so far: 14722.0
If we subtract 1050 from 1395, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 8:
525 can be fit into 3450 6 times, resulting in a remainder of 300.
Use 6 as the next digit of our solution. 
Result so far: 14722.6
The remainder is 300 after subtracting 3150 from 3450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 9:
525 can be fit into 3000 5 times, resulting in a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 14722.65
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.

Let's proceed to step 10:
The number 525 fits into 3750 7 times, leaving a remainder of 75.
Put 7 as the next digit of the answer. 
Result so far: 14722.657
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.

Going ahead to step 11:
When dividing 750 by 525, we get 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 14722.6571
The remainder is 225 after subtracting 525 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 12:
2250 divided by 525 is 4 with a remainder of 150.
Write down 4 as next digit of the result. 
Result so far: 14722.65714
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.

Let's proceed to step 13:
1500 divided by 525 is 2 with a remainder of 450.
The number 2 becomes the next digit in our result. 
Result so far: 14722.657142
Subtract 1050 from 1500 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

Let's proceed to step 14:
4500 divided by 525 is 8 with a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 14722.6571428
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.

Let's proceed to step 15:
525 goes into 3000 5 times with a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 14722.65714285
If we subtract 2625 from 3000, 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.

After the division, we end up with 14722.65714285 and a remainder of 3.75e-07.
