We divide 863952 by 10
We want to figure out the number of times 863952 can be divided by 10.

Moving on to step 1:
10 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 10

Advancing to step 2:
When dividing 86 by 10, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 80 from 86, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 10

Going ahead to step 3:
When dividing 63 by 10, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtracting 60 from 63 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 10

Advancing to step 4:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 863.0
Subtracting 30 from 39 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 10

Let's proceed to step 5:
10 goes into 95 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 8639.0
If we subtract 90 from 95, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 10

On to step 6:
The number 10 fits into 52 5 times, leaving a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 86395.0
If we subtract 50 from 52, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 10, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 86395.2
Deduct 20 from 20 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:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 86395.2
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.

Going ahead to step 9:
10 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 86395.2
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.

Our division results in 86395.2 with a remaining 0.0.
