We're dividing 878925 by 10 
We're looking to find how many times 10 goes into 878925.

Going ahead to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 10

Advancing to step 2:
10 can be fit into 87 8 times, resulting in a remainder of 7.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 80 from 87 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 10

Going ahead to step 3:
10 can be fit into 78 7 times, resulting in a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
The remainder is 8 after subtracting 70 from 78.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 10

Moving on to step 4:
10 goes into 89 8 times with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 878.0
If we subtract 80 from 89, we get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 10

Moving on to step 5:
The number 10 fits into 92 9 times, leaving a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 8789.0
The remainder is 2 after subtracting 90 from 92.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 10

On to step 6:
The number 10 fits into 25 2 times, leaving a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 87892.0
Subtract 20 from 25 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 10 fits into 50 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 87892.5
Deduct 50 from 50 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.

On to step 8:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 87892.5
Deduct 0 from 0 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.

Let's proceed to step 9:
When dividing 0 by 10, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 87892.5
Subtracting 0 from 0 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.

Our division results in 87892.5 with a remaining 0.0.
