We look at the division of 23899542 by 325 
The aim is to understand the frequency of 325 in 23899542.

Let's proceed to step 1:
When dividing 2 by 325, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 325

Going ahead to step 2:
If we divide 23 by 325, we get 0 and a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 325

Step 3:
325 goes into 238 0 times with a remainder of 238.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 238 to get 238.
Include the next digit (9) from the dividend after 238, then repeat: 2389 / 325

Advancing to step 4:
2389 divided by 325 is 7 with a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 2275 away from 2389, we end up with 114.
Take the next digit (9) from the dividend and append it to 114, then repeat: 1149 / 325

On to step 5:
325 can be fit into 1149 3 times, resulting in a remainder of 174.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 174 after subtracting 975 from 1149.
Bring next digit (5) of the dividend behind the 174 and repeat the process: 1745 / 325

Going ahead to step 6:
The number 325 fits into 1745 5 times, leaving a remainder of 120.
The next digit of our result is 5. 
Result so far: 735.0
If we take 1625 away from 1745, we end up with 120.
Take the next digit (4) from the dividend and append it to 120, then repeat: 1204 / 325

Advancing to step 7:
The number 325 fits into 1204 3 times, leaving a remainder of 229.
Use 3 as the next digit of our solution. 
Result so far: 7353.0
Subtract 975 from 1204 to get 229.
Append the next digit (2) from the dividend to 229 and continue with: 2292 / 325

Step 8:
325 goes into 2292 7 times with a remainder of 17.
The next digit of our result is 7. 
Result so far: 73537.0
Subtract 2275 from 2292 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
325 goes into 170 0 times with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 73537.0
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 10:
1700 divided by 325 is 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 73537.05
If we subtract 1625 from 1700, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 11:
750 divided by 325 is 2 with a remainder of 100.
The next digit of our result is 2. 
Result so far: 73537.052
Deduct 650 from 750 and we're left with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
325 goes into 1000 3 times with a remainder of 25.
The next digit of our result is 3. 
Result so far: 73537.0523
Subtract 975 from 1000 to 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.

Advancing to step 13:
The number 325 fits into 250 0 times, leaving a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 73537.0523
Subtracting 0 from 250 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 14:
325 can be fit into 2500 7 times, resulting in a remainder of 225.
Write down 7 as next digit of the result. 
Result so far: 73537.052307
If we take 2275 away from 2500, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Going ahead to step 15:
When dividing 2250 by 325, we get 6 with a remainder of 300.
Write down 6 as next digit of the result. 
Result so far: 73537.0523076
If we subtract 1950 from 2250, 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.

Going ahead to step 16:
3000 divided by 325 is 9 with a remainder of 75.
Use 9 as the next digit of our solution. 
Result so far: 73537.05230769
Subtracting 2925 from 3000 leaves us 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.

The final outcome is 73537.05230769, with a leftover of 7.5e-08.
