Let's divide 872815 by 25
We want to figure out the number of times 872815 can be divided by 25.

Step 1:
8 divided by 25 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 25

Let's proceed to step 2:
25 goes into 87 3 times with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 75 from 87 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 25

Let's proceed to step 3:
When dividing 122 by 25, we get 4 with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 100 from 122 and we're left with 22.
Grab the next digit (8) from the dividend, add it to 22, then carry on: 228 / 25

Advancing to step 4:
228 divided by 25 is 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 349.0
The remainder is 3 after subtracting 225 from 228.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 25

Step 5:
25 goes into 31 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 3491.0
Deduct 25 from 31 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 25

Moving on to step 6:
The number 25 fits into 65 2 times, leaving a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 34912.0
If we subtract 50 from 65, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
When dividing 150 by 25, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 34912.6
Deduct 150 from 150 and we're left 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.

Going ahead to step 8:
If we divide 0 by 25, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 34912.6
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.

Moving on 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: 34912.6
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 34912.6 with a remaining 0.0.
