We look at the division of 737658 by 25 
The aim is to understand the frequency of 25 in 737658.

Step 1:
The number 25 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 25

Advancing to step 2:
If we divide 73 by 25, we get 2 and a remainder of 23.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 50 away from 73, we end up with 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 25

On to step 3:
25 goes into 237 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 29.0
Subtract 225 from 237 to get 12.
Append the next digit (6) from the dividend to 12 and continue with: 126 / 25

Moving on to step 4:
25 can be fit into 126 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 295.0
The remainder is 1 after subtracting 125 from 126.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 25

Let's proceed to step 5:
If we divide 15 by 25, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 2950.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 25

Let's proceed to step 6:
25 can be fit into 158 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 29506.0
Deduct 150 from 158 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
If we divide 80 by 25, we get 3 and a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 29506.3
Subtract 75 from 80 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 29506.32
Subtracting 50 from 50 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.

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: 29506.32
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 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 29506.32
The remainder is 0 after subtracting 0 from 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 29506.32, with a leftover of 0.0.
