We look at the division of 291230 by 52 
The aim is to understand the frequency of 52 in 291230.

Advancing to step 1:
The number 52 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 52

Going ahead to step 2:
29 divided by 52 is 0 with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 52

Advancing to step 3:
291 divided by 52 is 5 with a remainder of 31.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 31 after subtracting 260 from 291.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 52

Going ahead to step 4:
When dividing 312 by 52, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 312 from 312 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 52

Moving on to step 5:
3 divided by 52 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 560.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 52

On to step 6:
52 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5600.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
300 divided by 52 is 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 5600.5
Subtracting 260 from 300 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
If we divide 400 by 52, we get 7 and a remainder of 36.
The number 7 becomes the next digit in our result. 
Result so far: 5600.57
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
52 can be fit into 360 6 times, resulting in a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 5600.576
If we take 312 away from 360, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
When dividing 480 by 52, we get 9 with a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 5600.5769
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
52 can be fit into 120 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 5600.57692
Subtracting 104 from 120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
52 goes into 160 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 5600.576923
The remainder is 4 after subtracting 156 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
52 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 5600.576923
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
52 can be fit into 400 7 times, resulting in a remainder of 36.
Write down 7 as next digit of the result. 
Result so far: 5600.57692307
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 5600.57692307 with a remainder of 3.6e-08.
