We divide 801393 by 25
The aim is to understand the frequency of 25 in 801393.

Let's proceed to step 1:
When dividing 8 by 25, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 25

On to step 2:
The number 25 fits into 80 3 times, leaving a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 75 from 80, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 25

Let's proceed to step 3:
The number 25 fits into 51 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 32.0
If we take 50 away from 51, we end up with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 25

Advancing to step 4:
If we divide 13 by 25, we get 0 and a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 320.0
The remainder is 13 after subtracting 0 from 13.
Take the next digit (9) from the dividend and append it to 13, then repeat: 139 / 25

Moving on to step 5:
When dividing 139 by 25, we get 5 with a remainder of 14.
The next digit of our result is 5. 
Result so far: 3205.0
Deduct 125 from 139 and we're left with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 25

Let's proceed to step 6:
25 goes into 143 5 times with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 32055.0
If we take 125 away from 143, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
25 can be fit into 180 7 times, resulting in a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 32055.7
Subtracting 175 from 180 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 25 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 32055.72
If we subtract 50 from 50, 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.

Advancing to step 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 32055.72
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:
When dividing 0 by 25, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32055.72
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.

Our division results in 32055.72 with a remaining 0.0.
