We look at the division of 22959065 by 321 
The aim is to understand the frequency of 321 in 22959065.

Let's proceed to step 1:
321 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 321

Let's proceed to step 2:
The number 321 fits into 22 0 times, leaving a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 321

Advancing to step 3:
If we divide 229 by 321, we get 0 and a remainder of 229.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 229 after subtracting 0 from 229.
Append the next digit (5) from the dividend to 229 and continue with: 2295 / 321

Let's proceed to step 4:
The number 321 fits into 2295 7 times, leaving a remainder of 48.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 2247 from 2295 and we're left with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 321

Advancing to step 5:
The number 321 fits into 489 1 times, leaving a remainder of 168.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
The remainder is 168 after subtracting 321 from 489.
Grab the next digit (0) from the dividend, add it to 168, then carry on: 1680 / 321

Moving on to step 6:
1680 divided by 321 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 715.0
Subtract 1605 from 1680 to get 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 321

Going ahead to step 7:
756 divided by 321 is 2 with a remainder of 114.
Write down 2 as next digit of the result. 
Result so far: 7152.0
Subtracting 642 from 756 leaves us with 114.
Append the next digit (5) from the dividend to 114 and continue with: 1145 / 321

On to step 8:
321 can be fit into 1145 3 times, resulting in a remainder of 182.
The number 3 becomes the next digit in our result. 
Result so far: 71523.0
Subtracting 963 from 1145 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 9:
321 goes into 1820 5 times with a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 71523.5
The remainder is 215 after subtracting 1605 from 1820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 10:
321 goes into 2150 6 times with a remainder of 224.
Write down 6 as next digit of the result. 
Result so far: 71523.56
If we subtract 1926 from 2150, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 11:
321 goes into 2240 6 times with a remainder of 314.
Write down 6 as next digit of the result. 
Result so far: 71523.566
If we subtract 1926 from 2240, we get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

After the division, we end up with 71523.566 and a remainder of 0.0314.
