672814 ÷ 25 
The aim is to understand the frequency of 25 in 672814.

Step 1:
The number 25 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 25

Going ahead 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
If we take 50 away from 67, we end up with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 25

On to step 3:
172 divided by 25 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 150 away from 172, we end up with 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 25

Let's proceed to step 4:
If we divide 228 by 25, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 269.0
The remainder is 3 after subtracting 225 from 228.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 25

Advancing to step 5:
The number 25 fits into 31 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 2691.0
Subtracting 25 from 31 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 25

Advancing to step 6:
25 goes into 64 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 26912.0
The remainder is 14 after subtracting 50 from 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
When dividing 140 by 25, we get 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 26912.5
Deduct 125 from 140 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
150 divided by 25 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 26912.56
The remainder is 0 after subtracting 150 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
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: 26912.56
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.

On to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 26912.56
Subtracting 0 from 0 leaves us 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 26912.56 with a remaining 0.0.
