Let's divide 919394 by 25
The aim is to understand the frequency of 25 in 919394.

Going ahead to step 1:
If we divide 9 by 25, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 25

On to step 2:
91 divided by 25 is 3 with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 75 from 91 and we're left with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 25

Moving on to step 3:
25 can be fit into 169 6 times, resulting in a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 150 from 169 to get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 25

Advancing to step 4:
25 can be fit into 193 7 times, resulting in a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 367.0
If we subtract 175 from 193, we get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 25

On to step 5:
189 divided by 25 is 7 with a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 3677.0
If we take 175 away from 189, we end up with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 25

Going ahead to step 6:
If we divide 144 by 25, we get 5 and a remainder of 19.
The next digit of our result is 5. 
Result so far: 36775.0
If we take 125 away from 144, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
If we divide 190 by 25, we get 7 and a remainder of 15.
The next digit of our result is 7. 
Result so far: 36775.7
If we take 175 away from 190, we end up 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.

Going ahead to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 36775.76
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.

Moving on to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 36775.76
The remainder is 0 after subtracting 0 from 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:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 36775.76
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 final result is 36775.76 with a remainder of 0.0.
