3729463 ÷ 323 
The aim is to understand the frequency of 323 in 3729463.

Let's proceed to step 1:
The number 323 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 323

Moving on to step 2:
When dividing 37 by 323, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 37 leaves us with 37.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 323

Moving on to step 3:
372 divided by 323 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 323 from 372 leaves us with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 323

On to step 4:
323 goes into 499 1 times with a remainder of 176.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
The remainder is 176 after subtracting 323 from 499.
Fetch the next digit (4) from the dividend, attach it to 176 and continue: 1764 / 323

Let's proceed to step 5:
When dividing 1764 by 323, we get 5 with a remainder of 149.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 1615 from 1764 leaves us with 149.
Include the next digit (6) from the dividend after 149, then repeat: 1496 / 323

Step 6:
323 can be fit into 1496 4 times, resulting in a remainder of 204.
Record the quotient 4 as the next digit in the result. 
Result so far: 1154.0
Deduct 1292 from 1496 and we're left with 204.
Bring next digit (3) of the dividend behind the 204 and repeat the process: 2043 / 323

On to step 7:
If we divide 2043 by 323, we get 6 and a remainder of 105.
Put 6 as the next digit of the answer. 
Result so far: 11546.0
The remainder is 105 after subtracting 1938 from 2043.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 8:
323 can be fit into 1050 3 times, resulting in a remainder of 81.
The next digit of our result is 3. 
Result so far: 11546.3
The remainder is 81 after subtracting 969 from 1050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
When dividing 810 by 323, we get 2 with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 11546.32
Subtracting 646 from 810 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 10:
323 goes into 1640 5 times with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 11546.325
Subtract 1615 from 1640 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.

Going ahead to step 11:
When dividing 250 by 323, we get 0 with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 11546.325
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.

Going ahead to step 12:
When dividing 2500 by 323, we get 7 with a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 11546.32507
Subtract 2261 from 2500 to get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 13:
323 can be fit into 2390 7 times, resulting in a remainder of 129.
Put 7 as the next digit of the answer. 
Result so far: 11546.325077
If we take 2261 away from 2390, we end up with 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

The final outcome is 11546.325077, with a leftover of 1.29e-05.
