222885 divided by 25 
The aim is to understand the frequency of 25 in 222885.

On to step 1:
If we divide 2 by 25, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 25

Advancing to step 2:
If we divide 22 by 25, we get 0 and a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 22 and we're left with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 25

Moving on to step 3:
The number 25 fits into 222 8 times, leaving a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 200 from 222, we get 22.
Fetch the next digit (8) from the dividend, attach it to 22 and continue: 228 / 25

Step 4:
The number 25 fits into 228 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 3 after subtracting 225 from 228.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 25

Step 5:
When dividing 38 by 25, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 891.0
If we subtract 25 from 38, we get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 25

Advancing to step 6:
135 divided by 25 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8915.0
Deduct 125 from 135 and we're left 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.

Step 7:
If we divide 100 by 25, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 8915.4
Subtract 100 from 100 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.

Advancing to step 8:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8915.4
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.

On to step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8915.4
If we subtract 0 from 0, we 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 8915.4 and a remainder of 0.0.
