We're dividing 513666 by 1 
Our goal is to divide 513666 by 1.

On to step 1:
The number 1 fits into 5 5 times, leaving 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.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Moving on to step 2:
When dividing 1 by 1, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 51.0
The remainder is 0 after subtracting 1 from 1.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 513.0
If we take 3 away from 3, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Advancing to step 4:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 5136.0
If we subtract 6 from 6, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Going ahead to step 5:
The number 1 fits into 6 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 51366.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Let's proceed to step 6:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 513666.0
If we subtract 6 from 6, we 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.

Let's proceed to step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 513666.0
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.

Advancing to step 8:
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: 513666.0
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.

The quotient of the division is 513666.0, and the remainder is 0.0.
