604240 ÷ 48 
We want to divide 604240 by 48.

Step 1:
6 divided by 48 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 48

Going ahead to step 2:
When dividing 60 by 48, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 48 from 60 and we're left with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 48

On to step 3:
124 divided by 48 is 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 96 from 124 and we're left with 28.
Append the next digit (2) from the dividend to 28 and continue with: 282 / 48

Step 4:
The number 48 fits into 282 5 times, leaving a remainder of 42.
The next digit of our result is 5. 
Result so far: 125.0
The remainder is 42 after subtracting 240 from 282.
Take the next digit (4) from the dividend and append it to 42, then repeat: 424 / 48

Step 5:
If we divide 424 by 48, we get 8 and a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 1258.0
Deduct 384 from 424 and we're left with 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 48

Going ahead to step 6:
48 can be fit into 400 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 12588.0
Subtracting 384 from 400 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 12588.3
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
48 goes into 160 3 times with a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 12588.33
Deduct 144 from 160 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 12588.33 with a remainder of 0.016.
