Let's divide 861008 by 2
We want to divide 861008 by 2.

Advancing to step 1:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 8 away from 8, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Step 2:
When dividing 6 by 2, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we subtract 6 from 6, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 2

Step 3:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 430.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Advancing to step 4:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4305.0
Deduct 10 from 10 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 2

On to step 5:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 43050.0
Deduct 0 from 0 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Let's proceed to step 6:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 430504.0
Deduct 8 from 8 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.

Moving on to step 7:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 430504.0
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.

Step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 430504.0
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 430504.0 with a remaining 0.0.
