761898 divided by 25 
The aim is to understand the frequency of 25 in 761898.

On to step 1:
The number 25 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 25

Advancing to step 2:
76 divided by 25 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 1 after subtracting 75 from 76.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 25

Step 3:
The number 25 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 30.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 25

Moving on to step 4:
The number 25 fits into 118 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 304.0
The remainder is 18 after subtracting 100 from 118.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 25

Advancing to step 5:
25 can be fit into 189 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 3047.0
Deduct 175 from 189 and we're left with 14.
Bring next digit (8) of the dividend behind the 14 and repeat the process: 148 / 25

Going ahead to step 6:
148 divided by 25 is 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 30475.0
Subtract 125 from 148 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 7:
The number 25 fits into 230 9 times, leaving a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 30475.9
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
When dividing 50 by 25, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 30475.92
If we take 50 away from 50, 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.

Going ahead to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30475.92
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.

Step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 30475.92
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 30475.92 with a remaining 0.0.
