Let's divide 15372313 by 513
The aim is to understand the frequency of 513 in 15372313.

Moving on to step 1:
513 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 513

Advancing to step 2:
513 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 513

Moving on to step 3:
153 divided by 513 is 0 with a remainder of 153.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 153 leaves us with 153.
Fetch the next digit (7) from the dividend, attach it to 153 and continue: 1537 / 513

Going ahead to step 4:
513 can be fit into 1537 2 times, resulting in a remainder of 511.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 1026 from 1537 to get 511.
Take the next digit (2) from the dividend and append it to 511, then repeat: 5112 / 513

Moving on to step 5:
5112 divided by 513 is 9 with a remainder of 495.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 4617 from 5112 leaves us with 495.
Include the next digit (3) from the dividend after 495, then repeat: 4953 / 513

Advancing to step 6:
513 can be fit into 4953 9 times, resulting in a remainder of 336.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
Subtract 4617 from 4953 to get 336.
Fetch the next digit (1) from the dividend, attach it to 336 and continue: 3361 / 513

Let's proceed to step 7:
3361 divided by 513 is 6 with a remainder of 283.
Put 6 as the next digit of the answer. 
Result so far: 2996.0
Deduct 3078 from 3361 and we're left with 283.
Include the next digit (3) from the dividend after 283, then repeat: 2833 / 513

Let's proceed to step 8:
When dividing 2833 by 513, we get 5 with a remainder of 268.
Record the quotient 5 as the next digit in the result. 
Result so far: 29965.0
If we subtract 2565 from 2833, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

On to step 9:
If we divide 2680 by 513, we get 5 and a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 29965.5
Subtracting 2565 from 2680 leaves us with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

On to step 10:
The number 513 fits into 1150 2 times, leaving a remainder of 124.
Write down 2 as next digit of the result. 
Result so far: 29965.52
Subtract 1026 from 1150 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 11:
513 goes into 1240 2 times with a remainder of 214.
Put 2 as the next digit of the answer. 
Result so far: 29965.522
Subtract 1026 from 1240 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

In conclusion, the division gives 29965.522 with a balance of 0.0214.
