861626 divided by 2 
Our goal is to divide 861626 by 2.

Let's proceed to step 1:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

On to step 2:
2 can be fit into 6 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Going ahead to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 430.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Step 4:
2 can be fit into 16 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 4308.0
The remainder is 0 after subtracting 16 from 16.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Advancing to step 5:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 43081.0
The remainder is 0 after subtracting 2 from 2.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Let's proceed to step 6:
The number 2 fits into 6 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 430813.0
If we take 6 away from 6, we end up 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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 430813.0
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:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 430813.0
If we take 0 away from 0, we end up 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 430813.0 with a remaining 0.0.
