We're dividing 673916 by 25 
The aim is to understand the frequency of 25 in 673916.

Going ahead to step 1:
6 divided by 25 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 25

Advancing to step 2:
The number 25 fits into 67 2 times, leaving a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 50 from 67 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 25

On to step 3:
173 divided by 25 is 6 with a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 150 from 173 to get 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 25

Going ahead to step 4:
If we divide 239 by 25, we get 9 and a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 269.0
Subtracting 225 from 239 leaves us with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 25

Step 5:
25 can be fit into 141 5 times, resulting in a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 2695.0
The remainder is 16 after subtracting 125 from 141.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 25

Let's proceed to step 6:
25 can be fit into 166 6 times, resulting in a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 26956.0
If we take 150 away from 166, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
25 can be fit into 160 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 26956.6
Subtracting 150 from 160 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.

Let's proceed to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 26956.64
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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26956.64
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.

Moving on to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 26956.64
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 quotient of the division is 26956.64, and the remainder is 0.0.
