We divide 846642 by 2
Let's see how many times 2 fits into 846642.

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
Deduct 8 from 8 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Going ahead to step 2:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 0 after subtracting 4 from 4.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Moving on to step 3:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Deduct 6 from 6 and we're left with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

Advancing to step 4:
2 goes into 6 3 times with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 4233.0
The remainder is 0 after subtracting 6 from 6.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 2

On to step 5:
2 can be fit into 4 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 42332.0
The remainder is 0 after subtracting 4 from 4.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 2

Going ahead to step 6:
The number 2 fits into 2 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 423321.0
The remainder is 0 after subtracting 2 from 2.
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 423321.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 423321.0
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.

After the division, we end up with 423321.0 and a remainder of 0.0.
