Let's divide 37647128 by 525
The aim is to understand the frequency of 525 in 37647128.

Advancing to step 1:
The number 525 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 525

Moving on to step 2:
When dividing 37 by 525, we get 0 with a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 37, we get 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 525

On to step 3:
525 goes into 376 0 times with a remainder of 376.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 376, we end up with 376.
Bring next digit (4) of the dividend behind the 376 and repeat the process: 3764 / 525

Advancing to step 4:
If we divide 3764 by 525, we get 7 and a remainder of 89.
The next digit of our result is 7. 
Result so far: 7.0
If we take 3675 away from 3764, we end up with 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 525

Let's proceed to step 5:
897 divided by 525 is 1 with a remainder of 372.
Write down 1 as next digit of the result. 
Result so far: 71.0
If we subtract 525 from 897, we get 372.
Take the next digit (1) from the dividend and append it to 372, then repeat: 3721 / 525

Let's proceed to step 6:
When dividing 3721 by 525, we get 7 with a remainder of 46.
Write down 7 as next digit of the result. 
Result so far: 717.0
If we subtract 3675 from 3721, we get 46.
Fetch the next digit (2) from the dividend, attach it to 46 and continue: 462 / 525

Let's proceed to step 7:
525 goes into 462 0 times with a remainder of 462.
Put 0 as the next digit of the answer. 
Result so far: 7170.0
If we take 0 away from 462, we end up with 462.
Fetch the next digit (8) from the dividend, attach it to 462 and continue: 4628 / 525

Going ahead to step 8:
When dividing 4628 by 525, we get 8 with a remainder of 428.
Write down 8 as next digit of the result. 
Result so far: 71708.0
If we subtract 4200 from 4628, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Moving on to step 9:
4280 divided by 525 is 8 with a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 71708.8
Deduct 4200 from 4280 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 525 is 1 with a remainder of 275.
Write down 1 as next digit of the result. 
Result so far: 71708.81
Subtracting 525 from 800 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 11:
The number 525 fits into 2750 5 times, leaving a remainder of 125.
The next digit of our result is 5. 
Result so far: 71708.815
The remainder is 125 after subtracting 2625 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 12:
1250 divided by 525 is 2 with a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 71708.8152
Subtract 1050 from 1250 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 13:
2000 divided by 525 is 3 with a remainder of 425.
The next digit of our result is 3. 
Result so far: 71708.81523
The remainder is 425 after subtracting 1575 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 14:
If we divide 4250 by 525, we get 8 and a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 71708.815238
The remainder is 50 after subtracting 4200 from 4250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 15:
The number 525 fits into 500 0 times, leaving a remainder of 500.
The number 0 becomes the next digit in our result. 
Result so far: 71708.815238
If we take 0 away from 500, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 16:
525 goes into 5000 9 times with a remainder of 275.
Record the quotient 9 as the next digit in the result. 
Result so far: 71708.81523809
Subtract 4725 from 5000 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

The final result is 71708.81523809 with a remainder of 2.75e-07.
