We're dividing 579316 by 25 
The aim is to understand the frequency of 25 in 579316.

Step 1:
If we divide 5 by 25, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 25

Let's proceed to step 2:
25 goes into 57 2 times with a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 50 from 57 to get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 25

Let's proceed to step 3:
When dividing 79 by 25, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 75 from 79, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 25

Advancing to step 4:
43 divided by 25 is 1 with a remainder of 18.
The next digit of our result is 1. 
Result so far: 231.0
If we take 25 away from 43, we end up with 18.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 25

Going ahead to step 5:
181 divided by 25 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 2317.0
If we subtract 175 from 181, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 25

Let's proceed to step 6:
If we divide 66 by 25, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 23172.0
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:
The number 25 fits into 160 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 23172.6
Deduct 150 from 160 and we're left with 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 8:
100 divided by 25 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 23172.64
If we subtract 100 from 100, we 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.

Step 9:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 23172.64
If we subtract 0 from 0, we 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.

Let's proceed to step 10:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23172.64
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 23172.64 with a remaining 0.0.
