We divide 19868379 by 525
The aim is to understand the frequency of 525 in 19868379.

Advancing to step 1:
525 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 525

Let's proceed to step 2:
525 can be fit into 19 0 times, resulting in a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 525

Let's proceed to step 3:
198 divided by 525 is 0 with a remainder of 198.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 198 after subtracting 0 from 198.
Include the next digit (6) from the dividend after 198, then repeat: 1986 / 525

Let's proceed to step 4:
The number 525 fits into 1986 3 times, leaving a remainder of 411.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 1575 from 1986 to get 411.
Append the next digit (8) from the dividend to 411 and continue with: 4118 / 525

Moving on to step 5:
If we divide 4118 by 525, we get 7 and a remainder of 443.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
The remainder is 443 after subtracting 3675 from 4118.
Grab the next digit (3) from the dividend, add it to 443, then carry on: 4433 / 525

Moving on to step 6:
525 goes into 4433 8 times with a remainder of 233.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
If we take 4200 away from 4433, we end up with 233.
Include the next digit (7) from the dividend after 233, then repeat: 2337 / 525

Going ahead to step 7:
The number 525 fits into 2337 4 times, leaving a remainder of 237.
The next digit of our result is 4. 
Result so far: 3784.0
If we subtract 2100 from 2337, we get 237.
Take the next digit (9) from the dividend and append it to 237, then repeat: 2379 / 525

Let's proceed to step 8:
The number 525 fits into 2379 4 times, leaving a remainder of 279.
Record the quotient 4 as the next digit in the result. 
Result so far: 37844.0
The remainder is 279 after subtracting 2100 from 2379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Step 9:
If we divide 2790 by 525, we get 5 and a remainder of 165.
Write down 5 as next digit of the result. 
Result so far: 37844.5
If we subtract 2625 from 2790, we get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Moving on to step 10:
If we divide 1650 by 525, we get 3 and a remainder of 75.
Record the quotient 3 as the next digit in the result. 
Result so far: 37844.53
Subtracting 1575 from 1650 leaves us 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.

Step 11:
750 divided by 525 is 1 with a remainder of 225.
The next digit of our result is 1. 
Result so far: 37844.531
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.

Going ahead to step 12:
525 goes into 2250 4 times with a remainder of 150.
The next digit of our result is 4. 
Result so far: 37844.5314
Subtract 2100 from 2250 to get 150.
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:
If we divide 1500 by 525, we get 2 and a remainder of 450.
The number 2 becomes the next digit in our result. 
Result so far: 37844.53142
If we subtract 1050 from 1500, we 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.

Step 14:
When dividing 4500 by 525, we get 8 with a remainder of 300.
Record the quotient 8 as the next digit in the result. 
Result so far: 37844.531428
If we subtract 4200 from 4500, we get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
525 can be fit into 3000 5 times, resulting in a remainder of 375.
Put 5 as the next digit of the answer. 
Result so far: 37844.5314285
The remainder is 375 after subtracting 2625 from 3000.
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 16:
525 goes into 3750 7 times with a remainder of 75.
The number 7 becomes the next digit in our result. 
Result so far: 37844.53142857
Subtracting 3675 from 3750 leaves us 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.

After the division, we end up with 37844.53142857 and a remainder of 7.5e-08.
