We're dividing 838418 by 25 
The aim is to understand the frequency of 25 in 838418.

On to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 25

Let's proceed to step 2:
25 goes into 83 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 75 from 83 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 25

Let's proceed to step 3:
When dividing 88 by 25, we get 3 with a remainder of 13.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 75 away from 88, we end up with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 25

Let's proceed to step 4:
25 goes into 134 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 335.0
If we subtract 125 from 134, we get 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 25

Going ahead to step 5:
25 goes into 91 3 times with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3353.0
If we subtract 75 from 91, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 25

Step 6:
The number 25 fits into 168 6 times, leaving a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 33536.0
Deduct 150 from 168 and we're left 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.

Advancing to step 7:
If we divide 180 by 25, we get 7 and a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 33536.7
If we take 175 away from 180, we end up 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.

On to step 8:
If we divide 50 by 25, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 33536.72
Deduct 50 from 50 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.

On to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 33536.72
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.

Advancing to step 10:
0 divided by 25 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 33536.72
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.

The final outcome is 33536.72, with a leftover of 0.0.
