Let's divide 859316 by 25
The aim is to understand the frequency of 25 in 859316.

Step 1:
If we divide 8 by 25, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 25

Advancing to step 2:
25 can be fit into 85 3 times, resulting in a remainder of 10.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 10 after subtracting 75 from 85.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 25

Moving on to step 3:
If we divide 109 by 25, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 34.0
The remainder is 9 after subtracting 100 from 109.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 25

Going ahead to step 4:
25 can be fit into 93 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 343.0
Subtract 75 from 93 to get 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 25

Moving on to step 5:
The number 25 fits into 181 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 3437.0
Subtracting 175 from 181 leaves us with 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 25

Going ahead to step 6:
The number 25 fits into 66 2 times, leaving a remainder of 16.
The next digit of our result is 2. 
Result so far: 34372.0
Deduct 50 from 66 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 7:
25 can be fit into 160 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 34372.6
If we subtract 150 from 160, we 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.

Step 8:
When dividing 100 by 25, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 34372.64
If we take 100 away from 100, 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.

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: 34372.64
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.

Going ahead to step 10:
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: 34372.64
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 quotient of the division is 34372.64, and the remainder is 0.0.
