Let's divide 2146956 by 25
The aim is to understand the frequency of 25 in 2146956.

Going ahead to step 1:
25 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 25

Advancing to step 2:
25 can be fit into 21 0 times, resulting in a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Append the next digit (4) from the dividend to 21 and continue with: 214 / 25

Let's proceed to step 3:
If we divide 214 by 25, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 200 away from 214, we end up with 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 25

Step 4:
The number 25 fits into 146 5 times, leaving a remainder of 21.
Put 5 as the next digit of the answer. 
Result so far: 85.0
The remainder is 21 after subtracting 125 from 146.
Include the next digit (9) from the dividend after 21, then repeat: 219 / 25

Moving on to step 5:
25 can be fit into 219 8 times, resulting in a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 858.0
The remainder is 19 after subtracting 200 from 219.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 25

Let's proceed to step 6:
When dividing 195 by 25, we get 7 with a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 8587.0
Subtracting 175 from 195 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 25

Advancing to step 7:
When dividing 206 by 25, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 85878.0
Deduct 200 from 206 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
25 can be fit into 60 2 times, resulting in a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 85878.2
If we subtract 50 from 60, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
If we divide 100 by 25, we get 4 and a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 85878.24
Deduct 100 from 100 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.

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: 85878.24
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.

Advancing to step 11:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85878.24
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.

After the division, we end up with 85878.24 and a remainder of 0.0.
