We look at the division of 573346 by 1 
We're looking to find how many times 1 goes into 573346.

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
If we take 5 away from 5, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

On to step 2:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 57.0
If we take 7 away from 7, we end up with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Moving on to step 3:
1 goes into 3 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 573.0
Deduct 3 from 3 and we're left with 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Moving on to step 4:
1 can be fit into 3 3 times, resulting in a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 5733.0
If we subtract 3 from 3, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Advancing to step 5:
1 can be fit into 4 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 57334.0
Subtract 4 from 4 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Going ahead to step 6:
If we divide 6 by 1, we get 6 and a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 573346.0
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.

Advancing 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: 573346.0
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.
Write down 0 as next digit of the result. 
Result so far: 573346.0
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.

After the division, we end up with 573346.0 and a remainder of 0.0.
