We divide 489127 by 525
The aim is to understand the frequency of 525 in 489127.

Going ahead to step 1:
When dividing 4 by 525, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 525

Going ahead to step 2:
525 can be fit into 48 0 times, resulting in a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (9) of the dividend behind the 48 and repeat the process: 489 / 525

Advancing to step 3:
When dividing 489 by 525, we get 0 with a remainder of 489.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 489 leaves us with 489.
Take the next digit (1) from the dividend and append it to 489, then repeat: 4891 / 525

Let's proceed to step 4:
4891 divided by 525 is 9 with a remainder of 166.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtracting 4725 from 4891 leaves us with 166.
Grab the next digit (2) from the dividend, add it to 166, then carry on: 1662 / 525

Let's proceed to step 5:
1662 divided by 525 is 3 with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 93.0
Subtracting 1575 from 1662 leaves us with 87.
Bring next digit (7) of the dividend behind the 87 and repeat the process: 877 / 525

Let's proceed to step 6:
525 goes into 877 1 times with a remainder of 352.
Use 1 as the next digit of our solution. 
Result so far: 931.0
Subtracting 525 from 877 leaves us with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 7:
525 can be fit into 3520 6 times, resulting in a remainder of 370.
Use 6 as the next digit of our solution. 
Result so far: 931.6
The remainder is 370 after subtracting 3150 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 8:
3700 divided by 525 is 7 with a remainder of 25.
The next digit of our result is 7. 
Result so far: 931.67
Subtracting 3675 from 3700 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
525 can be fit into 250 0 times, resulting in a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 931.67
Deduct 0 from 250 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
The number 525 fits into 2500 4 times, leaving a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 931.6704
If we subtract 2100 from 2500, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
If we divide 4000 by 525, we get 7 and a remainder of 325.
Put 7 as the next digit of the answer. 
Result so far: 931.67047
If we take 3675 away from 4000, we end up with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Step 12:
The number 525 fits into 3250 6 times, leaving a remainder of 100.
Use 6 as the next digit of our solution. 
Result so far: 931.670476
If we subtract 3150 from 3250, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 13:
When dividing 1000 by 525, we get 1 with a remainder of 475.
Put 1 as the next digit of the answer. 
Result so far: 931.6704761
If we take 525 away from 1000, we end up with 475.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Moving on to step 14:
If we divide 4750 by 525, we get 9 and a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 931.67047619
Deduct 4725 from 4750 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 931.67047619 with a remaining 2.5e-08.
