647636 divided by 5 
We want to figure out the number of times 647636 can be divided by 5.

Step 1:
When dividing 6 by 5, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 5 from 6, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 5

Step 2:
When dividing 14 by 5, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 10 from 14 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 5

Going ahead to step 3:
When dividing 47 by 5, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 129.0
If we take 45 away from 47, we end up with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 5

Let's proceed to step 4:
26 divided by 5 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 1295.0
If we take 25 away from 26, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 5

Going ahead to step 5:
5 goes into 13 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 12952.0
Subtract 10 from 13 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 5

Going ahead to step 6:
5 can be fit into 36 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 129527.0
Deduct 35 from 36 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 5 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 129527.2
Subtract 10 from 10 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.

Moving on to step 8:
The number 5 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 129527.2
Subtract 0 from 0 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.

On to step 9:
5 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 129527.2
Subtract 0 from 0 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.

Our division results in 129527.2 with a remaining 0.0.
