We divide 75245548 by 525
The aim is to understand the frequency of 525 in 75245548.

On to step 1:
When dividing 7 by 525, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (5) of the dividend behind the 7 and repeat the process: 75 / 525

Let's proceed to step 2:
525 can be fit into 75 0 times, resulting in a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 75 after subtracting 0 from 75.
Include the next digit (2) from the dividend after 75, then repeat: 752 / 525

Let's proceed to step 3:
525 can be fit into 752 1 times, resulting in a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 525 from 752 leaves us with 227.
Grab the next digit (4) from the dividend, add it to 227, then carry on: 2274 / 525

Going ahead to step 4:
525 goes into 2274 4 times with a remainder of 174.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 2100 from 2274, we get 174.
Grab the next digit (5) from the dividend, add it to 174, then carry on: 1745 / 525

Advancing to step 5:
525 goes into 1745 3 times with a remainder of 170.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
If we subtract 1575 from 1745, we get 170.
Grab the next digit (5) from the dividend, add it to 170, then carry on: 1705 / 525

Step 6:
If we divide 1705 by 525, we get 3 and a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 1433.0
Deduct 1575 from 1705 and we're left with 130.
Fetch the next digit (4) from the dividend, attach it to 130 and continue: 1304 / 525

Let's proceed to step 7:
1304 divided by 525 is 2 with a remainder of 254.
Put 2 as the next digit of the answer. 
Result so far: 14332.0
If we subtract 1050 from 1304, we get 254.
Take the next digit (8) from the dividend and append it to 254, then repeat: 2548 / 525

Step 8:
525 goes into 2548 4 times with a remainder of 448.
The next digit of our result is 4. 
Result so far: 143324.0
Subtracting 2100 from 2548 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Going ahead to step 9:
If we divide 4480 by 525, we get 8 and a remainder of 280.
Use 8 as the next digit of our solution. 
Result so far: 143324.8
If we subtract 4200 from 4480, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 10:
If we divide 2800 by 525, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 143324.85
Subtract 2625 from 2800 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Let's proceed to step 11:
525 can be fit into 1750 3 times, resulting in a remainder of 175.
Record the quotient 3 as the next digit in the result. 
Result so far: 143324.853
Subtract 1575 from 1750 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Moving on to step 12:
If we divide 1750 by 525, we get 3 and a remainder of 175.
Use 3 as the next digit of our solution. 
Result so far: 143324.8533
If we take 1575 away from 1750, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Our division results in 143324.8533 with a remaining 0.00175.
