Let's divide 802961 by 25
The aim is to understand the frequency of 25 in 802961.

Moving on to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 25

Moving on to step 2:
If we divide 80 by 25, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 75 away from 80, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 25

Let's proceed to step 3:
52 divided by 25 is 2 with a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 2 after subtracting 50 from 52.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 25

Step 4:
25 can be fit into 29 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 321.0
Deduct 25 from 29 and we're left with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 25

Advancing to step 5:
If we divide 46 by 25, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 3211.0
If we subtract 25 from 46, we get 21.
Fetch the next digit (1) from the dividend, attach it to 21 and continue: 211 / 25

Moving on to step 6:
25 goes into 211 8 times with a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 32118.0
Subtract 200 from 211 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
25 can be fit into 110 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 32118.4
Subtract 100 from 110 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 25, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 32118.44
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.

Our division results in 32118.44 with a remaining 0.0.
