52110 divided by 15 
The aim is to understand the frequency of 15 in 52110.

Let's proceed to step 1:
15 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 15

Step 2:
The number 15 fits into 52 3 times, leaving a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 45 away from 52, we end up with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 15

Let's proceed to step 3:
71 divided by 15 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 60 from 71, we get 11.
Append the next digit (1) from the dividend to 11 and continue with: 111 / 15

On to step 4:
If we divide 111 by 15, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 347.0
The remainder is 6 after subtracting 105 from 111.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 15

Advancing to step 5:
If we divide 60 by 15, we get 4 and a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 3474.0
Subtracting 60 from 60 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 6:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3474.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3474.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3474.0 and a remainder of 0.0.
