520331 ÷ 52 
The aim is to understand the frequency of 52 in 520331.

Going ahead to step 1:
5 divided by 52 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 52

Step 2:
52 goes into 52 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 52 from 52, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 52

Let's proceed to step 3:
The number 52 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 0, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 52

Let's proceed to step 4:
The number 52 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 52

Moving on to step 5:
52 goes into 33 0 times with a remainder of 33.
The next digit of our result is 0. 
Result so far: 1000.0
If we subtract 0 from 33, we get 33.
Grab the next digit (1) from the dividend, add it to 33, then carry on: 331 / 52

Moving on to step 6:
331 divided by 52 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 10006.0
Subtracting 312 from 331 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
The number 52 fits into 190 3 times, leaving a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 10006.3
If we subtract 156 from 190, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
If we divide 340 by 52, we get 6 and a remainder of 28.
Write down 6 as next digit of the result. 
Result so far: 10006.36
If we take 312 away from 340, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
If we divide 280 by 52, we get 5 and a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10006.365
Subtracting 260 from 280 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
52 goes into 200 3 times with a remainder of 44.
The next digit of our result is 3. 
Result so far: 10006.3653
If we subtract 156 from 200, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 11:
440 divided by 52 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 10006.36538
Deduct 416 from 440 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 12:
52 goes into 240 4 times with a remainder of 32.
The next digit of our result is 4. 
Result so far: 10006.365384
If we take 208 away from 240, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 52 is 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 10006.3653846
Deduct 312 from 320 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
When dividing 80 by 52, we get 1 with a remainder of 28.
Use 1 as the next digit of our solution. 
Result so far: 10006.36538461
If we take 52 away from 80, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 10006.36538461 with a balance of 2.8e-08.
