856868 ÷ 1 
We're looking to find how many times 1 goes into 856868.

On to step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Step 2:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

Step 3:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 856.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 4:
1 goes into 8 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8568.0
Subtracting 8 from 8 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

On to step 5:
1 goes into 6 6 times with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 85686.0
The remainder is 0 after subtracting 6 from 6.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

On to step 6:
The number 1 fits into 8 8 times, leaving a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 856868.0
Subtract 8 from 8 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.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 856868.0
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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 856868.0
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 856868.0 with a remaining 0.0.
