We divide 18953439 by 525
The aim is to understand the frequency of 525 in 18953439.

Step 1:
525 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 525

Going ahead to step 2:
525 can be fit into 18 0 times, resulting in a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 525

Going ahead to step 3:
The number 525 fits into 189 0 times, leaving a remainder of 189.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 189 and we're left with 189.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 525

On to step 4:
525 goes into 1895 3 times with a remainder of 320.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 1575 away from 1895, we end up with 320.
Fetch the next digit (3) from the dividend, attach it to 320 and continue: 3203 / 525

Going ahead to step 5:
3203 divided by 525 is 6 with a remainder of 53.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 53 after subtracting 3150 from 3203.
Grab the next digit (4) from the dividend, add it to 53, then carry on: 534 / 525

Advancing to step 6:
525 can be fit into 534 1 times, resulting in a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 361.0
Subtracting 525 from 534 leaves us with 9.
Bring next digit (3) of the dividend behind the 9 and repeat the process: 93 / 525

Step 7:
525 goes into 93 0 times with a remainder of 93.
The number 0 becomes the next digit in our result. 
Result so far: 3610.0
The remainder is 93 after subtracting 0 from 93.
Include the next digit (9) from the dividend after 93, then repeat: 939 / 525

Moving on to step 8:
525 goes into 939 1 times with a remainder of 414.
Put 1 as the next digit of the answer. 
Result so far: 36101.0
Subtract 525 from 939 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

On to step 9:
When dividing 4140 by 525, we get 7 with a remainder of 465.
Put 7 as the next digit of the answer. 
Result so far: 36101.7
Subtracting 3675 from 4140 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Step 10:
If we divide 4650 by 525, we get 8 and a remainder of 450.
The number 8 becomes the next digit in our result. 
Result so far: 36101.78
If we take 4200 away from 4650, we end up 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.

On to step 11:
If we divide 4500 by 525, we get 8 and a remainder of 300.
Put 8 as the next digit of the answer. 
Result so far: 36101.788
Subtracting 4200 from 4500 leaves us 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.

After the division, we end up with 36101.788 and a remainder of 0.03.
