880016 divided by 25 
The aim is to understand the frequency of 25 in 880016.

Going ahead to step 1:
When dividing 8 by 25, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 25

Moving on to step 2:
When dividing 88 by 25, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 75 from 88 to get 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 25

Moving on to step 3:
130 divided by 25 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtract 125 from 130 to get 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 25

Moving on to step 4:
25 can be fit into 50 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 352.0
If we subtract 50 from 50, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 25

Going ahead to step 5:
If we divide 1 by 25, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 3520.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 25

On to step 6:
If we divide 16 by 25, we get 0 and a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 35200.0
If we take 0 away from 16, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
160 divided by 25 is 6 with a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 35200.6
Subtracting 150 from 160 leaves us with 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 8:
The number 25 fits into 100 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 35200.64
If we take 100 away from 100, we end up 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.

Moving on to step 9:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 35200.64
If we take 0 away from 0, we end up 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 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: 35200.64
If we take 0 away from 0, we end up 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.

The final outcome is 35200.64, with a leftover of 0.0.
