We're dividing 442484 by 2 
We want to figure out the number of times 442484 can be divided by 2.

Step 1:
4 divided by 2 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 2

Moving on to step 2:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Advancing to step 3:
If we divide 2 by 2, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 221.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Advancing to step 4:
If we divide 4 by 2, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2212.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Going ahead to step 5:
2 goes into 8 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 22124.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Advancing to step 6:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 221242.0
Deduct 4 from 4 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.

Advancing to step 7:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 221242.0
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.

On to step 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 221242.0
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.

The final outcome is 221242.0, with a leftover of 0.0.
