We're dividing 320397 by 57 
We're looking to find how many times 57 goes into 320397.

On to step 1:
The number 57 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 57

Advancing to step 2:
57 goes into 32 0 times with a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 32 after subtracting 0 from 32.
Fetch the next digit (0) from the dividend, attach it to 32 and continue: 320 / 57

Moving on to step 3:
320 divided by 57 is 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtract 285 from 320 to get 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 57

Let's proceed to step 4:
The number 57 fits into 353 6 times, leaving a remainder of 11.
The next digit of our result is 6. 
Result so far: 56.0
The remainder is 11 after subtracting 342 from 353.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 57

Moving on to step 5:
The number 57 fits into 119 2 times, leaving a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 562.0
Deduct 114 from 119 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 57

Going ahead to step 6:
The number 57 fits into 57 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 5621.0
Subtracting 57 from 57 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.

Advancing to step 7:
57 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 5621.0
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.

Going ahead to step 8:
If we divide 0 by 57, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 5621.0
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.

Our division results in 5621.0 with a remaining 0.0.
