We look at the division of 47854866 by 525 
The aim is to understand the frequency of 525 in 47854866.

Moving on to step 1:
The number 525 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 525

Moving on to step 2:
525 can be fit into 47 0 times, resulting in a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 47 and we're left with 47.
Take the next digit (8) from the dividend and append it to 47, then repeat: 478 / 525

Going ahead to step 3:
525 goes into 478 0 times with a remainder of 478.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 478, we get 478.
Take the next digit (5) from the dividend and append it to 478, then repeat: 4785 / 525

Let's proceed to step 4:
The number 525 fits into 4785 9 times, leaving a remainder of 60.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 4725 from 4785 to get 60.
Append the next digit (4) from the dividend to 60 and continue with: 604 / 525

Let's proceed to step 5:
525 goes into 604 1 times with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
If we subtract 525 from 604, we get 79.
Include the next digit (8) from the dividend after 79, then repeat: 798 / 525

Advancing to step 6:
When dividing 798 by 525, we get 1 with a remainder of 273.
Put 1 as the next digit of the answer. 
Result so far: 911.0
If we take 525 away from 798, we end up with 273.
Take the next digit (6) from the dividend and append it to 273, then repeat: 2736 / 525

Advancing to step 7:
The number 525 fits into 2736 5 times, leaving a remainder of 111.
Record the quotient 5 as the next digit in the result. 
Result so far: 9115.0
Deduct 2625 from 2736 and we're left with 111.
Bring next digit (6) of the dividend behind the 111 and repeat the process: 1116 / 525

Moving on to step 8:
1116 divided by 525 is 2 with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 91152.0
Subtract 1050 from 1116 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 9:
The number 525 fits into 660 1 times, leaving a remainder of 135.
Write down 1 as next digit of the result. 
Result so far: 91152.1
The remainder is 135 after subtracting 525 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Step 10:
525 goes into 1350 2 times with a remainder of 300.
Record the quotient 2 as the next digit in the result. 
Result so far: 91152.12
If we subtract 1050 from 1350, 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.

Step 11:
525 goes into 3000 5 times with a remainder of 375.
The number 5 becomes the next digit in our result. 
Result so far: 91152.125
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.

Let's proceed to step 12:
3750 divided by 525 is 7 with a remainder of 75.
Use 7 as the next digit of our solution. 
Result so far: 91152.1257
If we take 3675 away from 3750, we end up 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.

On to step 13:
The number 525 fits into 750 1 times, leaving a remainder of 225.
The number 1 becomes the next digit in our result. 
Result so far: 91152.12571
Subtract 525 from 750 to 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.

Moving on to step 14:
525 goes into 2250 4 times with a remainder of 150.
Record the quotient 4 as the next digit in the result. 
Result so far: 91152.125714
If we subtract 2100 from 2250, we 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.

On to step 15:
The number 525 fits into 1500 2 times, leaving a remainder of 450.
Write down 2 as next digit of the result. 
Result so far: 91152.1257142
Deduct 1050 from 1500 and we're left 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.

Step 16:
The number 525 fits into 4500 8 times, leaving a remainder of 300.
The number 8 becomes the next digit in our result. 
Result so far: 91152.12571428
The remainder is 300 after subtracting 4200 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

The final result is 91152.12571428 with a remainder of 3e-07.
