We're dividing 33457402 by 25 
The aim is to understand the frequency of 25 in 33457402.

Going ahead to step 1:
25 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 25

Step 2:
The number 25 fits into 33 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 25 away from 33, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 25

Step 3:
When dividing 84 by 25, we get 3 with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 75 from 84 leaves us with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 25

Advancing to step 4:
The number 25 fits into 95 3 times, leaving a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 133.0
If we take 75 away from 95, we end up with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 25

Moving on to step 5:
207 divided by 25 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1338.0
The remainder is 7 after subtracting 200 from 207.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 25

Step 6:
25 goes into 74 2 times with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 13382.0
The remainder is 24 after subtracting 50 from 74.
Grab the next digit (0) from the dividend, add it to 24, then carry on: 240 / 25

Step 7:
If we divide 240 by 25, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 133829.0
The remainder is 15 after subtracting 225 from 240.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 25

Going ahead to step 8:
When dividing 152 by 25, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1338296.0
Subtracting 150 from 152 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 25 is 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1338296.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1338296.08
The remainder is 0 after subtracting 200 from 200.
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 11:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1338296.08
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.

Step 12:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1338296.08
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 1338296.08 with a balance of 0.0.
