We look at the division of 551185 by 1 
We're looking to find how many times 1 goes into 551185.

Moving on to step 1:
1 goes into 5 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Let's proceed to step 2:
When dividing 5 by 1, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
Subtracting 5 from 5 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Moving on to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 551.0
Subtracting 1 from 1 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Moving on to step 4:
1 goes into 1 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 5511.0
Subtract 1 from 1 to get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Let's proceed to step 5:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 55118.0
Subtract 8 from 8 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Advancing to step 6:
If we divide 5 by 1, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 551185.0
The remainder is 0 after subtracting 5 from 5.
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:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 551185.0
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.

Advancing to step 8:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 551185.0
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.

The final outcome is 551185.0, with a leftover of 0.0.
