We look at the division of 51860 by 25 
The aim is to understand the frequency of 25 in 51860.

Step 1:
If we divide 5 by 25, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 25

Advancing to step 2:
25 goes into 51 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 50 from 51 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 25

On to step 3:
If we divide 18 by 25, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 25

Going ahead to step 4:
When dividing 186 by 25, we get 7 with a remainder of 11.
The next digit of our result is 7. 
Result so far: 207.0
If we take 175 away from 186, we end up with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 25

Let's proceed to step 5:
110 divided by 25 is 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 2074.0
The remainder is 10 after subtracting 100 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 6:
25 can be fit into 100 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 2074.4
Deduct 100 from 100 and we're left 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.

Step 7:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2074.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2074.4
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.

In conclusion, the division gives 2074.4 with a balance of 0.0.
