814160 ÷ 25 
The aim is to understand the frequency of 25 in 814160.

Let's proceed to step 1:
8 divided by 25 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 25

On to step 2:
If we divide 81 by 25, we get 3 and a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 75 from 81 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 25

On to step 3:
25 can be fit into 64 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
If we subtract 50 from 64, we get 14.
Fetch the next digit (1) from the dividend, attach it to 14 and continue: 141 / 25

Advancing to step 4:
25 goes into 141 5 times with a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 325.0
Subtract 125 from 141 to get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 25

On to step 5:
25 can be fit into 166 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 3256.0
Subtracting 150 from 166 leaves us with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 25

Step 6:
If we divide 160 by 25, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 32566.0
If we subtract 150 from 160, 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 7:
100 divided by 25 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 32566.4
If we subtract 100 from 100, 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.

On to step 8:
25 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 32566.4
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.

Step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32566.4
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.

Our division results in 32566.4 with a remaining 0.0.
