We're dividing 86253482 by 825 
The aim is to understand the frequency of 825 in 86253482.

Advancing to step 1:
When dividing 8 by 825, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 825

Moving on to step 2:
When dividing 86 by 825, we get 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Include the next digit (2) from the dividend after 86, then repeat: 862 / 825

Moving on to step 3:
862 divided by 825 is 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 825 from 862 to get 37.
Bring next digit (5) of the dividend behind the 37 and repeat the process: 375 / 825

On to step 4:
375 divided by 825 is 0 with a remainder of 375.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 375 and we're left with 375.
Bring next digit (3) of the dividend behind the 375 and repeat the process: 3753 / 825

Let's proceed to step 5:
The number 825 fits into 3753 4 times, leaving a remainder of 453.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
The remainder is 453 after subtracting 3300 from 3753.
Include the next digit (4) from the dividend after 453, then repeat: 4534 / 825

Moving on to step 6:
If we divide 4534 by 825, we get 5 and a remainder of 409.
Put 5 as the next digit of the answer. 
Result so far: 1045.0
Subtracting 4125 from 4534 leaves us with 409.
Include the next digit (8) from the dividend after 409, then repeat: 4098 / 825

On to step 7:
825 can be fit into 4098 4 times, resulting in a remainder of 798.
Write down 4 as next digit of the result. 
Result so far: 10454.0
Deduct 3300 from 4098 and we're left with 798.
Grab the next digit (2) from the dividend, add it to 798, then carry on: 7982 / 825

Going ahead to step 8:
825 goes into 7982 9 times with a remainder of 557.
Put 9 as the next digit of the answer. 
Result so far: 104549.0
Deduct 7425 from 7982 and we're left with 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5570, and continue the process.

Moving on to step 9:
5570 divided by 825 is 6 with a remainder of 620.
Use 6 as the next digit of our solution. 
Result so far: 104549.6
If we take 4950 away from 5570, we end up with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 10:
When dividing 6200 by 825, we get 7 with a remainder of 425.
Put 7 as the next digit of the answer. 
Result so far: 104549.67
The remainder is 425 after subtracting 5775 from 6200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 11:
4250 divided by 825 is 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 104549.675
Deduct 4125 from 4250 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 12:
When dividing 1250 by 825, we get 1 with a remainder of 425.
Record the quotient 1 as the next digit in the result. 
Result so far: 104549.6751
If we take 825 away from 1250, we end up with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Going ahead to step 13:
When dividing 4250 by 825, we get 5 with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 104549.67515
Subtract 4125 from 4250 to get 125.
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 14:
If we divide 1250 by 825, we get 1 and a remainder of 425.
Write down 1 as next digit of the result. 
Result so far: 104549.675151
If we subtract 825 from 1250, we get 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Step 15:
825 goes into 4250 5 times with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 104549.6751515
Subtracting 4125 from 4250 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 16:
When dividing 1250 by 825, we get 1 with a remainder of 425.
Put 1 as the next digit of the answer. 
Result so far: 104549.67515151
The remainder is 425 after subtracting 825 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

The quotient of the division is 104549.67515151, and the remainder is 4.25e-07.
