We look at the division of 550438 by 1 
We're looking to find how many times 1 goes into 550438.

Step 1:
When dividing 5 by 1, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

Let's proceed to step 2:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 5 from 5 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Going ahead to step 3:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 550.0
If we subtract 0 from 0, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 5504.0
Subtract 4 from 4 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Going ahead to step 5:
If we divide 3 by 1, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 55043.0
Subtracting 3 from 3 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

Let's proceed to step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 550438.0
Subtracting 8 from 8 leaves us 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.

On to step 7:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 550438.0
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.

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 550438.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 550438.0 and a remainder of 0.0.
