We're dividing 489478 by 57 
We're looking to find how many times 57 goes into 489478.

Let's proceed to step 1:
If we divide 4 by 57, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 57

Moving on to step 2:
57 goes into 48 0 times with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 57

Advancing to step 3:
When dividing 489 by 57, we get 8 with a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 456 from 489, we get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 57

Step 4:
57 goes into 334 5 times with a remainder of 49.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Deduct 285 from 334 and we're left with 49.
Append the next digit (7) from the dividend to 49 and continue with: 497 / 57

Step 5:
The number 57 fits into 497 8 times, leaving a remainder of 41.
Use 8 as the next digit of our solution. 
Result so far: 858.0
If we take 456 away from 497, we end up with 41.
Take the next digit (8) from the dividend and append it to 41, then repeat: 418 / 57

Going ahead to step 6:
If we divide 418 by 57, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 8587.0
If we subtract 399 from 418, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 57, we get 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 8587.3
The remainder is 19 after subtracting 171 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
If we divide 190 by 57, we get 3 and a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 8587.33
The remainder is 19 after subtracting 171 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 8587.33, with a leftover of 0.019.
