321685 divided by 25 
The aim is to understand the frequency of 25 in 321685.

Moving on to step 1:
The number 25 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 25

Let's proceed to step 2:
The number 25 fits into 32 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 25 from 32 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 25

On to step 3:
When dividing 71 by 25, we get 2 with a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 50 from 71 and we're left with 21.
Take the next digit (6) from the dividend and append it to 21, then repeat: 216 / 25

Moving on to step 4:
216 divided by 25 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 128.0
The remainder is 16 after subtracting 200 from 216.
Include the next digit (8) from the dividend after 16, then repeat: 168 / 25

Moving on to step 5:
168 divided by 25 is 6 with a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 1286.0
Subtract 150 from 168 to get 18.
Grab the next digit (5) from the dividend, add it to 18, then carry on: 185 / 25

Moving on to step 6:
25 goes into 185 7 times with a remainder of 10.
Record the quotient 7 as the next digit in the result. 
Result so far: 12867.0
The remainder is 10 after subtracting 175 from 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
25 goes into 100 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 12867.4
Subtract 100 from 100 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.

Let's proceed to 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: 12867.4
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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12867.4
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.

The quotient of the division is 12867.4, and the remainder is 0.0.
