642730 divided by 5 
Let's see how many times 5 fits into 642730.

Let's proceed to step 1:
The number 5 fits into 6 1 times, leaving a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 5 from 6 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 5

On to step 2:
5 can be fit into 14 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
If we take 10 away from 14, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 5

Going ahead to step 3:
The number 5 fits into 42 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 128.0
If we subtract 40 from 42, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 5

Going ahead to step 4:
If we divide 27 by 5, we get 5 and a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 1285.0
If we take 25 away from 27, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 5

On to step 5:
If we divide 23 by 5, we get 4 and a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 12854.0
If we take 20 away from 23, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 5

Going ahead to step 6:
The number 5 fits into 30 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 128546.0
Subtract 30 from 30 to 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.

Let's proceed to step 7:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 128546.0
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.

Let's proceed to step 8:
0 divided by 5 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 128546.0
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.

Our division results in 128546.0 with a remaining 0.0.
