On to step 1:
3 divided by 639 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 639

Going ahead to step 2:
639 goes into 38 0 times with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (1) from the dividend, attach it to 38 and continue: 381 / 639

Let's proceed to step 3:
381 divided by 639 is 0 with a remainder of 381.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 381, we end up with 381.
Take the next digit (3) from the dividend and append it to 381, then repeat: 3813 / 639

Step 4:
When dividing 3813 by 639, we get 5 with a remainder of 618.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 3195 from 3813 leaves us with 618.
Append the next digit (4) from the dividend to 618 and continue with: 6184 / 639

Let's proceed to step 5:
When dividing 6184 by 639, we get 9 with a remainder of 433.
Write down 9 as next digit of the result. 
Result so far: 59.0
Subtract 5751 from 6184 to get 433.
Append the next digit (5) from the dividend to 433 and continue with: 4335 / 639

Going ahead to step 6:
When dividing 4335 by 639, we get 6 with a remainder of 501.
Record the quotient 6 as the next digit in the result. 
Result so far: 596.0
Subtract 3834 from 4335 to get 501.
Fetch the next digit (2) from the dividend, attach it to 501 and continue: 5012 / 639

Let's proceed to step 7:
If we divide 5012 by 639, we get 7 and a remainder of 539.
Put 7 as the next digit of the answer. 
Result so far: 5967.0
Deduct 4473 from 5012 and we're left with 539.
Append the next digit (6) from the dividend to 539 and continue with: 5396 / 639

Moving on to step 8:
639 goes into 5396 8 times with a remainder of 284.
Record the quotient 8 as the next digit in the result. 
Result so far: 59678.0
Deduct 5112 from 5396 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 9:
The number 639 fits into 2840 4 times, leaving a remainder of 284.
Record the quotient 4 as the next digit in the result. 
Result so far: 59678.4
Subtracting 2556 from 2840 leaves us with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Moving on to step 10:
639 can be fit into 2840 4 times, resulting in a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 59678.44
Deduct 2556 from 2840 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The quotient of the division is 59678.44, and the remainder is 0.284.
