We divide 291002 by 25
The aim is to understand the frequency of 25 in 291002.

Going ahead to step 1:
When dividing 2 by 25, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 25

Step 2:
If we divide 29 by 25, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 25 from 29 leaves us with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 25

Step 3:
25 can be fit into 41 1 times, resulting in a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we subtract 25 from 41, we get 16.
Grab the next digit (0) from the dividend, add it to 16, then carry on: 160 / 25

Moving on to step 4:
The number 25 fits into 160 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 116.0
Subtract 150 from 160 to get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 25

Advancing to step 5:
100 divided by 25 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1164.0
The remainder is 0 after subtracting 100 from 100.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 25

Moving on to step 6:
25 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 11640.0
If we take 0 away from 2, we end up 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.

On to step 7:
When dividing 20 by 25, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 11640.0
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 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 11640.08
Subtract 200 from 200 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.

On to step 9:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11640.08
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.

On to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11640.08
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.

The final result is 11640.08 with a remainder of 0.0.
