Let's divide 11015 by 25
The aim is to understand the frequency of 25 in 11015.

Let's proceed to step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 25

On to step 2:
If we divide 11 by 25, we get 0 and a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 25

Advancing to step 3:
The number 25 fits into 110 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 100 from 110 leaves us with 10.
Bring next digit (1) of the dividend behind the 10 and repeat the process: 101 / 25

Let's proceed to step 4:
The number 25 fits into 101 4 times, leaving a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 100 from 101 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 25

Advancing to step 5:
When dividing 15 by 25, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 440.0
If we subtract 0 from 15, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 6:
150 divided by 25 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 440.6
If we take 150 away from 150, 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 7:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 440.6
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.

On to step 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 440.6
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.

After the division, we end up with 440.6 and a remainder of 0.0.
