We're dividing 5991093 by 323 
The aim is to understand the frequency of 323 in 5991093.

On to step 1:
The number 323 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 323

On to step 2:
When dividing 59 by 323, we get 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 59 leaves us with 59.
Include the next digit (9) from the dividend after 59, then repeat: 599 / 323

Let's proceed to step 3:
599 divided by 323 is 1 with a remainder of 276.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 323 from 599 and we're left with 276.
Take the next digit (1) from the dividend and append it to 276, then repeat: 2761 / 323

Let's proceed to step 4:
2761 divided by 323 is 8 with a remainder of 177.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 2584 from 2761 leaves us with 177.
Append the next digit (0) from the dividend to 177 and continue with: 1770 / 323

Advancing to step 5:
323 can be fit into 1770 5 times, resulting in a remainder of 155.
Write down 5 as next digit of the result. 
Result so far: 185.0
The remainder is 155 after subtracting 1615 from 1770.
Fetch the next digit (9) from the dividend, attach it to 155 and continue: 1559 / 323

Going ahead to step 6:
1559 divided by 323 is 4 with a remainder of 267.
The next digit of our result is 4. 
Result so far: 1854.0
The remainder is 267 after subtracting 1292 from 1559.
Include the next digit (3) from the dividend after 267, then repeat: 2673 / 323

Advancing to step 7:
If we divide 2673 by 323, we get 8 and a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 18548.0
The remainder is 89 after subtracting 2584 from 2673.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 8:
323 goes into 890 2 times with a remainder of 244.
The next digit of our result is 2. 
Result so far: 18548.2
The remainder is 244 after subtracting 646 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 9:
2440 divided by 323 is 7 with a remainder of 179.
The next digit of our result is 7. 
Result so far: 18548.27
Subtracting 2261 from 2440 leaves us with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 10:
1790 divided by 323 is 5 with a remainder of 175.
Use 5 as the next digit of our solution. 
Result so far: 18548.275
Subtract 1615 from 1790 to get 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Going ahead to step 11:
The number 323 fits into 1750 5 times, leaving a remainder of 135.
Use 5 as the next digit of our solution. 
Result so far: 18548.2755
Deduct 1615 from 1750 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

The final result is 18548.2755 with a remainder of 0.00135.
