Let's divide 453486 by 2
We want to divide 453486 by 2.

Moving on to step 1:
2 can be fit into 4 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Moving on to step 2:
2 goes into 5 2 times with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Deduct 4 from 5 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 2

On to step 3:
When dividing 13 by 2, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 226.0
If we take 12 away from 13, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Let's proceed to step 4:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 2267.0
If we take 14 away from 14, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

On to step 5:
When dividing 8 by 2, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 22674.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Going ahead to step 6:
If we divide 6 by 2, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 226743.0
If we subtract 6 from 6, 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.

Advancing to 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: 226743.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 226743.0
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.

The final result is 226743.0 with a remainder of 0.0.
