We divide 589921 by 25
The aim is to understand the frequency of 25 in 589921.

Step 1:
5 divided by 25 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 25

Step 2:
58 divided by 25 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 50 from 58 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 25

Going ahead to step 3:
25 goes into 89 3 times with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
The remainder is 14 after subtracting 75 from 89.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 25

On to step 4:
If we divide 149 by 25, we get 5 and a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 235.0
Subtract 125 from 149 to get 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 25

Step 5:
242 divided by 25 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 2359.0
Deduct 225 from 242 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 25

Let's proceed to step 6:
The number 25 fits into 171 6 times, leaving a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 23596.0
If we take 150 away from 171, we end up 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.

Moving on to step 7:
When dividing 210 by 25, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 23596.8
Subtracting 200 from 210 leaves us 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.

Going ahead to step 8:
100 divided by 25 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 23596.84
If we take 100 away from 100, 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.

Going ahead to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 23596.84
If we subtract 0 from 0, we 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 10:
If we divide 0 by 25, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 23596.84
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.

After the division, we end up with 23596.84 and a remainder of 0.0.
