455259 ÷ 57 
We want to figure out the number of times 455259 can be divided by 57.

Going ahead to step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 57

Moving on to step 2:
57 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Append the next digit (5) from the dividend to 45 and continue with: 455 / 57

Going ahead to step 3:
455 divided by 57 is 7 with a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 56 after subtracting 399 from 455.
Bring next digit (2) of the dividend behind the 56 and repeat the process: 562 / 57

Moving on to step 4:
57 goes into 562 9 times with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 79.0
Deduct 513 from 562 and we're left with 49.
Take the next digit (5) from the dividend and append it to 49, then repeat: 495 / 57

Step 5:
57 can be fit into 495 8 times, resulting in a remainder of 39.
Put 8 as the next digit of the answer. 
Result so far: 798.0
Deduct 456 from 495 and we're left with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 57

On to step 6:
57 goes into 399 7 times with a remainder of 0.
The next digit of our result is 7. 
Result so far: 7987.0
The remainder is 0 after subtracting 399 from 399.
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 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7987.0
If we take 0 away from 0, we end up 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.

Let's proceed to step 8:
0 divided by 57 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 7987.0
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.

The final result is 7987.0 with a remainder of 0.0.
