Let's divide 451189 by 2
Our goal is to divide 451189 by 2.

On to step 1:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 4 away from 4, we end up with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Step 2:
When dividing 5 by 2, we get 2 with a remainder of 1.
The next digit of our result is 2. 
Result so far: 22.0
Deduct 4 from 5 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

On to step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 225.0
Deduct 10 from 11 and we're left with 1.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 2

On to step 4:
When dividing 11 by 2, we get 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 2255.0
Subtracting 10 from 11 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Let's proceed to step 5:
2 goes into 18 9 times with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 22559.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 225594.0
Deduct 8 from 9 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 225594.5
The remainder is 0 after subtracting 10 from 10.
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 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 225594.5
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.

Going ahead to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 225594.5
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 225594.5 with a remaining 0.0.
