43817449 ÷ 325 
The aim is to understand the frequency of 325 in 43817449.

Going ahead to step 1:
4 divided by 325 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 325

Let's proceed to step 2:
43 divided by 325 is 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Bring next digit (8) of the dividend behind the 43 and repeat the process: 438 / 325

On to step 3:
The number 325 fits into 438 1 times, leaving a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 113 after subtracting 325 from 438.
Take the next digit (1) from the dividend and append it to 113, then repeat: 1131 / 325

Going ahead to step 4:
If we divide 1131 by 325, we get 3 and a remainder of 156.
Write down 3 as next digit of the result. 
Result so far: 13.0
The remainder is 156 after subtracting 975 from 1131.
Grab the next digit (7) from the dividend, add it to 156, then carry on: 1567 / 325

Step 5:
325 goes into 1567 4 times with a remainder of 267.
The next digit of our result is 4. 
Result so far: 134.0
Subtracting 1300 from 1567 leaves us with 267.
Take the next digit (4) from the dividend and append it to 267, then repeat: 2674 / 325

Let's proceed to step 6:
325 can be fit into 2674 8 times, resulting in a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 1348.0
The remainder is 74 after subtracting 2600 from 2674.
Include the next digit (4) from the dividend after 74, then repeat: 744 / 325

Let's proceed to step 7:
744 divided by 325 is 2 with a remainder of 94.
Put 2 as the next digit of the answer. 
Result so far: 13482.0
If we subtract 650 from 744, we get 94.
Bring next digit (9) of the dividend behind the 94 and repeat the process: 949 / 325

Going ahead to step 8:
When dividing 949 by 325, we get 2 with a remainder of 299.
Use 2 as the next digit of our solution. 
Result so far: 134822.0
The remainder is 299 after subtracting 650 from 949.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

On to step 9:
325 goes into 2990 9 times with a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 134822.9
Subtracting 2925 from 2990 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 10:
325 can be fit into 650 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 134822.92
Deduct 650 from 650 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
325 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 134822.92
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 325 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 134822.92
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 134822.92 with a remainder of 0.0.
