We look at the division of 578660 by 49 
Let's see how many times 49 fits into 578660.

Let's proceed to step 1:
If we divide 5 by 49, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 49

Moving on to step 2:
If we divide 57 by 49, we get 1 and a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 49 from 57, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 49

Going ahead to step 3:
49 can be fit into 88 1 times, resulting in a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 49 from 88 leaves us with 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 49

On to step 4:
49 can be fit into 396 8 times, resulting in a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
If we subtract 392 from 396, we get 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 49

Going ahead to step 5:
46 divided by 49 is 0 with a remainder of 46.
The next digit of our result is 0. 
Result so far: 1180.0
Subtract 0 from 46 to get 46.
Grab the next digit (0) from the dividend, add it to 46, then carry on: 460 / 49

Advancing to step 6:
49 goes into 460 9 times with a remainder of 19.
Write down 9 as next digit of the result. 
Result so far: 11809.0
The remainder is 19 after subtracting 441 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
49 goes into 190 3 times with a remainder of 43.
Record the quotient 3 as the next digit in the result. 
Result so far: 11809.3
The remainder is 43 after subtracting 147 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
If we divide 430 by 49, we get 8 and a remainder of 38.
Use 8 as the next digit of our solution. 
Result so far: 11809.38
Deduct 392 from 430 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
The number 49 fits into 380 7 times, leaving a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 11809.387
Subtracting 343 from 380 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 10:
49 goes into 370 7 times with a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 11809.3877
If we subtract 343 from 370, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

After the division, we end up with 11809.3877 and a remainder of 0.00027.
