553430 divided by 1 
Let's see how many times 1 fits into 553430.

Advancing to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing 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
Subtracting 5 from 5 leaves us with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 3:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 553.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 5534.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Moving on to step 5:
3 divided by 1 is 3 with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 55343.0
If we take 3 away from 3, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 1

Step 6:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 553430.0
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.

Let's proceed to step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 553430.0
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.

Let's proceed to step 8:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 553430.0
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.

The final outcome is 553430.0, with a leftover of 0.0.
