681985 divided by 25 
The aim is to understand the frequency of 25 in 681985.

On to step 1:
25 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 25

Let's proceed to step 2:
When dividing 68 by 25, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 50 from 68 leaves us with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 25

On to step 3:
When dividing 181 by 25, we get 7 with a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 175 from 181, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 25

On to step 4:
If we divide 69 by 25, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 272.0
The remainder is 19 after subtracting 50 from 69.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 25

Let's proceed to step 5:
198 divided by 25 is 7 with a remainder of 23.
The next digit of our result is 7. 
Result so far: 2727.0
The remainder is 23 after subtracting 175 from 198.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 25

Let's proceed to step 6:
If we divide 235 by 25, we get 9 and a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 27279.0
Subtract 225 from 235 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
The number 25 fits into 100 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 27279.4
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 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 27279.4
Deduct 0 from 0 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.

Let's proceed to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 27279.4
Deduct 0 from 0 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.

Our division results in 27279.4 with a remaining 0.0.
