Let's divide 780871 by 25
The aim is to understand the frequency of 25 in 780871.

Let's proceed to step 1:
25 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 25

Going ahead to step 2:
78 divided by 25 is 3 with a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtracting 75 from 78 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 25

Moving on to step 3:
25 can be fit into 30 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 25 from 30 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 25

Let's proceed to step 4:
25 can be fit into 58 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 312.0
If we take 50 away from 58, we end up with 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 25

Moving on to step 5:
87 divided by 25 is 3 with a remainder of 12.
The next digit of our result is 3. 
Result so far: 3123.0
Subtract 75 from 87 to get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 25

Let's proceed to step 6:
When dividing 121 by 25, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 31234.0
Subtracting 100 from 121 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
25 can be fit into 210 8 times, resulting in a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 31234.8
If we take 200 away from 210, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 25 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 31234.84
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31234.84
Deduct 0 from 0 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 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 31234.84
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.

The final result is 31234.84 with a remainder of 0.0.
