We look at the division of 551017 by 1 
Our goal is to divide 551017 by 1.

Going ahead to step 1:
1 can be fit into 5 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 5 from 5 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 1

On to step 2:
The number 1 fits into 5 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 55.0
Deduct 5 from 5 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 551.0
The remainder is 0 after subtracting 1 from 1.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 4:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5510.0
The remainder is 0 after subtracting 0 from 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Advancing to step 5:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 55101.0
If we subtract 1 from 1, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Moving on to step 6:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 551017.0
Subtracting 7 from 7 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.

Going ahead to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 551017.0
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.

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: 551017.0
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.

After the division, we end up with 551017.0 and a remainder of 0.0.
