Let's divide 21865134 by 323
The aim is to understand the frequency of 323 in 21865134.

Going ahead to step 1:
When dividing 2 by 323, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 323

Advancing to step 2:
If we divide 21 by 323, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 323

Let's proceed to step 3:
The number 323 fits into 218 0 times, leaving a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 218, we get 218.
Append the next digit (6) from the dividend to 218 and continue with: 2186 / 323

Let's proceed to step 4:
If we divide 2186 by 323, we get 6 and a remainder of 248.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 248 after subtracting 1938 from 2186.
Bring next digit (5) of the dividend behind the 248 and repeat the process: 2485 / 323

Advancing to step 5:
If we divide 2485 by 323, we get 7 and a remainder of 224.
The next digit of our result is 7. 
Result so far: 67.0
If we take 2261 away from 2485, we end up with 224.
Grab the next digit (1) from the dividend, add it to 224, then carry on: 2241 / 323

Let's proceed to step 6:
323 can be fit into 2241 6 times, resulting in a remainder of 303.
Record the quotient 6 as the next digit in the result. 
Result so far: 676.0
Subtracting 1938 from 2241 leaves us with 303.
Grab the next digit (3) from the dividend, add it to 303, then carry on: 3033 / 323

On to step 7:
323 can be fit into 3033 9 times, resulting in a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 6769.0
The remainder is 126 after subtracting 2907 from 3033.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 323

Step 8:
323 can be fit into 1264 3 times, resulting in a remainder of 295.
Write down 3 as next digit of the result. 
Result so far: 67693.0
If we take 969 away from 1264, we end up with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 9:
323 goes into 2950 9 times with a remainder of 43.
The number 9 becomes the next digit in our result. 
Result so far: 67693.9
The remainder is 43 after subtracting 2907 from 2950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 10:
When dividing 430 by 323, we get 1 with a remainder of 107.
The next digit of our result is 1. 
Result so far: 67693.91
Subtracting 323 from 430 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 11:
323 goes into 1070 3 times with a remainder of 101.
Write down 3 as next digit of the result. 
Result so far: 67693.913
If we take 969 away from 1070, we end up with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 12:
323 can be fit into 1010 3 times, resulting in a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 67693.9133
Subtracting 969 from 1010 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final result is 67693.9133 with a remainder of 0.00041.
