We divide 25250960 by 513
The aim is to understand the frequency of 513 in 25250960.

Moving on to step 1:
513 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 513

On to step 2:
When dividing 25 by 513, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 513

On to step 3:
The number 513 fits into 252 0 times, leaving a remainder of 252.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 252 after subtracting 0 from 252.
Append the next digit (5) from the dividend to 252 and continue with: 2525 / 513

Let's proceed to step 4:
If we divide 2525 by 513, we get 4 and a remainder of 473.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 473 after subtracting 2052 from 2525.
Append the next digit (0) from the dividend to 473 and continue with: 4730 / 513

Moving on to step 5:
When dividing 4730 by 513, we get 9 with a remainder of 113.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 4617 from 4730 to get 113.
Grab the next digit (9) from the dividend, add it to 113, then carry on: 1139 / 513

Going ahead to step 6:
513 can be fit into 1139 2 times, resulting in a remainder of 113.
Record the quotient 2 as the next digit in the result. 
Result so far: 492.0
The remainder is 113 after subtracting 1026 from 1139.
Grab the next digit (6) from the dividend, add it to 113, then carry on: 1136 / 513

Let's proceed to step 7:
The number 513 fits into 1136 2 times, leaving a remainder of 110.
Put 2 as the next digit of the answer. 
Result so far: 4922.0
If we subtract 1026 from 1136, we get 110.
Include the next digit (0) from the dividend after 110, then repeat: 1100 / 513

Step 8:
The number 513 fits into 1100 2 times, leaving a remainder of 74.
The number 2 becomes the next digit in our result. 
Result so far: 49222.0
The remainder is 74 after subtracting 1026 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
740 divided by 513 is 1 with a remainder of 227.
Record the quotient 1 as the next digit in the result. 
Result so far: 49222.1
If we take 513 away from 740, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

Advancing to step 10:
If we divide 2270 by 513, we get 4 and a remainder of 218.
Write down 4 as next digit of the result. 
Result so far: 49222.14
Deduct 2052 from 2270 and we're left with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 11:
513 can be fit into 2180 4 times, resulting in a remainder of 128.
Put 4 as the next digit of the answer. 
Result so far: 49222.144
The remainder is 128 after subtracting 2052 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

The final result is 49222.144 with a remainder of 0.0128.
