783125 divided by 25 
The aim is to understand the frequency of 25 in 783125.

Advancing to step 1:
25 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 25

Moving on to step 2:
25 goes into 78 3 times with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 75 from 78 to get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 25

On to step 3:
25 goes into 33 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 25 from 33, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 25

Let's proceed to step 4:
25 goes into 81 3 times with a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtract 75 from 81 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 25

Step 5:
25 goes into 62 2 times with a remainder of 12.
The number 2 becomes the next digit in our result. 
Result so far: 3132.0
Subtract 50 from 62 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 25

Let's proceed to step 6:
25 goes into 125 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 31325.0
Subtract 125 from 125 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.

Step 7:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31325.0
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 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 31325.0
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 31325.0 with a remainder of 0.0.
