We look at the division of 623880 by 329 
The aim is to understand the frequency of 329 in 623880.

Going ahead to step 1:
If we divide 6 by 329, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 329

Advancing to step 2:
62 divided by 329 is 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (3) from the dividend, add it to 62, then carry on: 623 / 329

Let's proceed to step 3:
329 goes into 623 1 times with a remainder of 294.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 329 from 623, we get 294.
Take the next digit (8) from the dividend and append it to 294, then repeat: 2948 / 329

Let's proceed to step 4:
If we divide 2948 by 329, we get 8 and a remainder of 316.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 316 after subtracting 2632 from 2948.
Grab the next digit (8) from the dividend, add it to 316, then carry on: 3168 / 329

Let's proceed to step 5:
When dividing 3168 by 329, we get 9 with a remainder of 207.
Write down 9 as next digit of the result. 
Result so far: 189.0
Subtract 2961 from 3168 to get 207.
Include the next digit (0) from the dividend after 207, then repeat: 2070 / 329

Advancing to step 6:
329 goes into 2070 6 times with a remainder of 96.
The next digit of our result is 6. 
Result so far: 1896.0
If we subtract 1974 from 2070, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 7:
When dividing 960 by 329, we get 2 with a remainder of 302.
The number 2 becomes the next digit in our result. 
Result so far: 1896.2
Subtract 658 from 960 to get 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 8:
If we divide 3020 by 329, we get 9 and a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 1896.29
The remainder is 59 after subtracting 2961 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 9:
When dividing 590 by 329, we get 1 with a remainder of 261.
Put 1 as the next digit of the answer. 
Result so far: 1896.291
Deduct 329 from 590 and we're left with 261.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2610, and continue the process.

Going ahead to step 10:
The number 329 fits into 2610 7 times, leaving a remainder of 307.
The next digit of our result is 7. 
Result so far: 1896.2917
The remainder is 307 after subtracting 2303 from 2610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 11:
3070 divided by 329 is 9 with a remainder of 109.
The number 9 becomes the next digit in our result. 
Result so far: 1896.29179
Subtract 2961 from 3070 to get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 12:
1090 divided by 329 is 3 with a remainder of 103.
The number 3 becomes the next digit in our result. 
Result so far: 1896.291793
If we subtract 987 from 1090, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 13:
When dividing 1030 by 329, we get 3 with a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 1896.2917933
If we take 987 away from 1030, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

In conclusion, the division gives 1896.2917933 with a balance of 4.3e-07.
