We look at the division of 864122 by 2 
Let's see how many times 2 fits into 864122.

Step 1:
When dividing 8 by 2, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 8 from 8 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Moving on to step 2:
2 goes into 6 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtract 6 from 6 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

Advancing to step 3:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 432.0
The remainder is 0 after subtracting 4 from 4.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 4320.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Step 5:
If we divide 12 by 2, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 43206.0
If we subtract 12 from 12, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Going ahead to step 6:
If we divide 2 by 2, we get 1 and a remainder of 0.
The next digit of our result is 1. 
Result so far: 432061.0
Deduct 2 from 2 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.

Step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 432061.0
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 432061.0
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.

The final outcome is 432061.0, with a leftover of 0.0.
