259844 ÷ 25 
The aim is to understand the frequency of 25 in 259844.

On to step 1:
If we divide 2 by 25, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 25

Step 2:
25 divided by 25 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 0 after subtracting 25 from 25.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 25

Step 3:
9 divided by 25 is 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 25

Advancing to step 4:
The number 25 fits into 98 3 times, leaving a remainder of 23.
The next digit of our result is 3. 
Result so far: 103.0
Deduct 75 from 98 and we're left with 23.
Fetch the next digit (4) from the dividend, attach it to 23 and continue: 234 / 25

Step 5:
25 can be fit into 234 9 times, resulting in a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
Deduct 225 from 234 and we're left with 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 25

Moving on to step 6:
25 can be fit into 94 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 10393.0
If we subtract 75 from 94, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
If we divide 190 by 25, we get 7 and a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 10393.7
If we subtract 175 from 190, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
If we divide 150 by 25, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 10393.76
If we take 150 away from 150, 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.

On to step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10393.76
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.

Moving on to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10393.76
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.

After the division, we end up with 10393.76 and a remainder of 0.0.
