Let's divide 779045 by 25
The aim is to understand the frequency of 25 in 779045.

Going ahead to step 1:
7 divided by 25 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 25

Advancing to step 2:
The number 25 fits into 77 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 75 from 77 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 25

Step 3:
The number 25 fits into 29 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 31.0
If we take 25 away from 29, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 25

Moving on to step 4:
If we divide 40 by 25, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 311.0
The remainder is 15 after subtracting 25 from 40.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 25

Step 5:
154 divided by 25 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3116.0
Subtract 150 from 154 to get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 25

Going ahead to step 6:
If we divide 45 by 25, we get 1 and a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31161.0
The remainder is 20 after subtracting 25 from 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
25 goes into 200 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 31161.8
Subtracting 200 from 200 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.

Moving on to step 8:
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: 31161.8
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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 31161.8
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 31161.8 with a remainder of 0.0.
