Let's divide 639287 by 5
Let's see how many times 5 fits into 639287.

On to step 1:
6 divided by 5 is 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 5 from 6 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 5

Let's proceed to step 2:
5 can be fit into 13 2 times, resulting in a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12.0
Subtract 10 from 13 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 5

Let's proceed to step 3:
39 divided by 5 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 127.0
Subtract 35 from 39 to get 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 5

Advancing to step 4:
5 can be fit into 42 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1278.0
Deduct 40 from 42 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 5

Going ahead to step 5:
28 divided by 5 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 12785.0
If we subtract 25 from 28, we get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 5

Advancing to step 6:
5 can be fit into 37 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 127857.0
The remainder is 2 after subtracting 35 from 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
5 can be fit into 20 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 127857.4
Deduct 20 from 20 and we're left 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.

On to step 8:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 127857.4
Deduct 0 from 0 and we're left 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.

Moving on to step 9:
If we divide 0 by 5, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 127857.4
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 127857.4, and the remainder is 0.0.
