Let's divide 45663922 by 525
The aim is to understand the frequency of 525 in 45663922.

On to step 1:
4 divided by 525 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 525

On to step 2:
45 divided by 525 is 0 with a remainder of 45.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Take the next digit (6) from the dividend and append it to 45, then repeat: 456 / 525

On to step 3:
If we divide 456 by 525, we get 0 and a remainder of 456.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 456 leaves us with 456.
Grab the next digit (6) from the dividend, add it to 456, then carry on: 4566 / 525

Advancing to step 4:
The number 525 fits into 4566 8 times, leaving a remainder of 366.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we take 4200 away from 4566, we end up with 366.
Bring next digit (3) of the dividend behind the 366 and repeat the process: 3663 / 525

Going ahead to step 5:
The number 525 fits into 3663 6 times, leaving a remainder of 513.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 3150 from 3663 and we're left with 513.
Include the next digit (9) from the dividend after 513, then repeat: 5139 / 525

Step 6:
The number 525 fits into 5139 9 times, leaving a remainder of 414.
Write down 9 as next digit of the result. 
Result so far: 869.0
If we take 4725 away from 5139, we end up with 414.
Bring next digit (2) of the dividend behind the 414 and repeat the process: 4142 / 525

Advancing to step 7:
If we divide 4142 by 525, we get 7 and a remainder of 467.
Write down 7 as next digit of the result. 
Result so far: 8697.0
If we take 3675 away from 4142, we end up with 467.
Bring next digit (2) of the dividend behind the 467 and repeat the process: 4672 / 525

Step 8:
When dividing 4672 by 525, we get 8 with a remainder of 472.
Put 8 as the next digit of the answer. 
Result so far: 86978.0
The remainder is 472 after subtracting 4200 from 4672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 9:
525 can be fit into 4720 8 times, resulting in a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 86978.8
If we take 4200 away from 4720, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
525 goes into 5200 9 times with a remainder of 475.
The next digit of our result is 9. 
Result so far: 86978.89
The remainder is 475 after subtracting 4725 from 5200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Advancing to step 11:
4750 divided by 525 is 9 with a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 86978.899
If we subtract 4725 from 4750, we get 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 86978.899 with a remaining 0.0025.
