We look at the division of 24495649 by 852 
The aim is to understand the frequency of 852 in 24495649.

On to step 1:
852 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 852

On to step 2:
The number 852 fits into 24 0 times, leaving a remainder of 24.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 24 after subtracting 0 from 24.
Grab the next digit (4) from the dividend, add it to 24, then carry on: 244 / 852

Let's proceed to step 3:
If we divide 244 by 852, we get 0 and a remainder of 244.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 244, we get 244.
Bring next digit (9) of the dividend behind the 244 and repeat the process: 2449 / 852

On to step 4:
If we divide 2449 by 852, we get 2 and a remainder of 745.
The next digit of our result is 2. 
Result so far: 2.0
If we take 1704 away from 2449, we end up with 745.
Take the next digit (5) from the dividend and append it to 745, then repeat: 7455 / 852

Advancing to step 5:
7455 divided by 852 is 8 with a remainder of 639.
The next digit of our result is 8. 
Result so far: 28.0
Subtract 6816 from 7455 to get 639.
Bring next digit (6) of the dividend behind the 639 and repeat the process: 6396 / 852

Moving on to step 6:
If we divide 6396 by 852, we get 7 and a remainder of 432.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
Deduct 5964 from 6396 and we're left with 432.
Include the next digit (4) from the dividend after 432, then repeat: 4324 / 852

On to step 7:
When dividing 4324 by 852, we get 5 with a remainder of 64.
Use 5 as the next digit of our solution. 
Result so far: 2875.0
If we subtract 4260 from 4324, we get 64.
Bring next digit (9) of the dividend behind the 64 and repeat the process: 649 / 852

Moving on to step 8:
When dividing 649 by 852, we get 0 with a remainder of 649.
The next digit of our result is 0. 
Result so far: 28750.0
Subtract 0 from 649 to get 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

Step 9:
When dividing 6490 by 852, we get 7 with a remainder of 526.
Record the quotient 7 as the next digit in the result. 
Result so far: 28750.7
Deduct 5964 from 6490 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Going ahead to step 10:
852 can be fit into 5260 6 times, resulting in a remainder of 148.
The next digit of our result is 6. 
Result so far: 28750.76
Deduct 5112 from 5260 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 11:
If we divide 1480 by 852, we get 1 and a remainder of 628.
Put 1 as the next digit of the answer. 
Result so far: 28750.761
Subtract 852 from 1480 to get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Going ahead to step 12:
852 can be fit into 6280 7 times, resulting in a remainder of 316.
Write down 7 as next digit of the result. 
Result so far: 28750.7617
Subtract 5964 from 6280 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Advancing to step 13:
3160 divided by 852 is 3 with a remainder of 604.
The number 3 becomes the next digit in our result. 
Result so far: 28750.76173
The remainder is 604 after subtracting 2556 from 3160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

Let's proceed to step 14:
If we divide 6040 by 852, we get 7 and a remainder of 76.
Put 7 as the next digit of the answer. 
Result so far: 28750.761737
Deduct 5964 from 6040 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
852 goes into 760 0 times with a remainder of 760.
The next digit of our result is 0. 
Result so far: 28750.761737
If we take 0 away from 760, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

On to step 16:
When dividing 7600 by 852, we get 8 with a remainder of 784.
Record the quotient 8 as the next digit in the result. 
Result so far: 28750.76173708
Deduct 6816 from 7600 and we're left with 784.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7840, and continue the process.

The final result is 28750.76173708 with a remainder of 7.84e-07.
