638395 ÷ 5 
Let's see how many times 5 fits into 638395.

On to step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 5 from 6.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 5

Going ahead to step 2:
When dividing 13 by 5, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 10 from 13 and we're left with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 5

Step 3:
When dividing 38 by 5, we get 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 127.0
The remainder is 3 after subtracting 35 from 38.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 5

On to step 4:
When dividing 33 by 5, we get 6 with a remainder of 3.
Use 6 as the next digit of our solution. 
Result so far: 1276.0
The remainder is 3 after subtracting 30 from 33.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 5

Going ahead to step 5:
5 goes into 39 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 12767.0
If we subtract 35 from 39, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 5

Moving on to step 6:
If we divide 45 by 5, we get 9 and a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 127679.0
If we take 45 away from 45, we end up 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.

Step 7:
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: 127679.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
5 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 127679.0
The remainder is 0 after subtracting 0 from 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 final result is 127679.0 with a remainder of 0.0.
