388782 ÷ 25 
The aim is to understand the frequency of 25 in 388782.

On to step 1:
3 divided by 25 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 25

Let's proceed to step 2:
25 goes into 38 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 25 from 38 and we're left with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 25

Going ahead to step 3:
When dividing 138 by 25, we get 5 with a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 125 from 138 to get 13.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 25

Let's proceed to step 4:
If we divide 137 by 25, we get 5 and a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 155.0
Subtract 125 from 137 to get 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 25

Step 5:
The number 25 fits into 128 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 1555.0
Subtracting 125 from 128 leaves us with 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 25

Step 6:
When dividing 32 by 25, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 15551.0
Subtract 25 from 32 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
If we divide 70 by 25, we get 2 and a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 15551.2
Subtracting 50 from 70 leaves us 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 8:
200 divided by 25 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 15551.28
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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15551.28
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.

On to step 10:
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: 15551.28
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 15551.28, with a leftover of 0.0.
