We divide 558040 by 1
We want to divide 558040 by 1.

On to step 1:
When dividing 5 by 1, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 5 from 5, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 1

Moving on to step 2:
If we divide 5 by 1, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 55.0
If we subtract 5 from 5, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Going ahead to step 3:
1 goes into 8 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 558.0
If we subtract 8 from 8, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Going ahead to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5580.0
Subtract 0 from 0 to get 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 5:
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: 55804.0
Deduct 4 from 4 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Advancing to step 6:
1 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 558040.0
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.

On to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 558040.0
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.

On to step 8:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 558040.0
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 outcome is 558040.0, with a leftover of 0.0.
