We look at the division of 52165843 by 328 
The aim is to understand the frequency of 328 in 52165843.

Let's proceed to step 1:
5 divided by 328 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 328

Moving on to step 2:
328 goes into 52 0 times with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Grab the next digit (1) from the dividend, add it to 52, then carry on: 521 / 328

On to step 3:
The number 328 fits into 521 1 times, leaving a remainder of 193.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 328 from 521, we get 193.
Fetch the next digit (6) from the dividend, attach it to 193 and continue: 1936 / 328

Moving on to step 4:
328 goes into 1936 5 times with a remainder of 296.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 1640 from 1936 leaves us with 296.
Fetch the next digit (5) from the dividend, attach it to 296 and continue: 2965 / 328

Moving on to step 5:
If we divide 2965 by 328, we get 9 and a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 159.0
If we take 2952 away from 2965, we end up with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 328

Let's proceed to step 6:
The number 328 fits into 138 0 times, leaving a remainder of 138.
The number 0 becomes the next digit in our result. 
Result so far: 1590.0
Subtract 0 from 138 to get 138.
Bring next digit (4) of the dividend behind the 138 and repeat the process: 1384 / 328

On to step 7:
1384 divided by 328 is 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 15904.0
Deduct 1312 from 1384 and we're left with 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 328

Let's proceed to step 8:
328 goes into 723 2 times with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 159042.0
If we subtract 656 from 723, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 9:
If we divide 670 by 328, we get 2 and a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 159042.2
Deduct 656 from 670 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
140 divided by 328 is 0 with a remainder of 140.
The next digit of our result is 0. 
Result so far: 159042.2
Subtracting 0 from 140 leaves us with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 11:
The number 328 fits into 1400 4 times, leaving a remainder of 88.
Record the quotient 4 as the next digit in the result. 
Result so far: 159042.204
Subtracting 1312 from 1400 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 12:
When dividing 880 by 328, we get 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 159042.2042
If we subtract 656 from 880, 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.

Going ahead to step 13:
If we divide 2240 by 328, we get 6 and a remainder of 272.
Record the quotient 6 as the next digit in the result. 
Result so far: 159042.20426
If we subtract 1968 from 2240, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Moving on to step 14:
The number 328 fits into 2720 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 159042.204268
Deduct 2624 from 2720 and we're left with 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 15:
When dividing 960 by 328, we get 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 159042.2042682
If we take 656 away from 960, we end up with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 16:
3040 divided by 328 is 9 with a remainder of 88.
The next digit of our result is 9. 
Result so far: 159042.20426829
Subtracting 2952 from 3040 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

After the division, we end up with 159042.20426829 and a remainder of 8.8e-08.
