880170 divided by 25 
The aim is to understand the frequency of 25 in 880170.

Going ahead to step 1:
25 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 25

Advancing to step 2:
25 goes into 88 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 75 from 88, we get 13.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 25

Going ahead to step 3:
When dividing 130 by 25, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 5 after subtracting 125 from 130.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 25

Step 4:
25 goes into 51 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 352.0
Subtracting 50 from 51 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 25

Moving on to step 5:
When dividing 17 by 25, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 3520.0
The remainder is 17 after subtracting 0 from 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 25

Moving on to step 6:
When dividing 170 by 25, we get 6 with a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 35206.0
Deduct 150 from 170 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.

Step 7:
The number 25 fits into 200 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 35206.8
Subtracting 200 from 200 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.

Let's proceed to step 8:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35206.8
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 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35206.8
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 quotient of the division is 35206.8, and the remainder is 0.0.
