615708 ÷ 25 
The aim is to understand the frequency of 25 in 615708.

Moving on to step 1:
25 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 25

Moving on to step 2:
When dividing 61 by 25, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 50 from 61 leaves us with 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 25

Let's proceed to step 3:
25 can be fit into 115 4 times, resulting in a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 100 from 115 and we're left with 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 25

Going ahead to step 4:
25 can be fit into 157 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 246.0
The remainder is 7 after subtracting 150 from 157.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 25

Step 5:
70 divided by 25 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2462.0
If we subtract 50 from 70, we get 20.
Include the next digit (8) from the dividend after 20, then repeat: 208 / 25

Advancing to step 6:
When dividing 208 by 25, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 24628.0
If we take 200 away from 208, we end up 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.

Step 7:
80 divided by 25 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 24628.3
Deduct 75 from 80 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
50 divided by 25 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 24628.32
The remainder is 0 after subtracting 50 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 24628.32
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.

Let's proceed to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 24628.32
If we take 0 away from 0, we end up 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.

The final result is 24628.32 with a remainder of 0.0.
