We divide 40308947 by 5
We want to figure out the number of times 40308947 can be divided by 5.

On to step 1:
5 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 5

Step 2:
When dividing 40 by 5, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 40 from 40 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 5

On to step 3:
The number 5 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 5

On to step 4:
When dividing 30 by 5, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 806.0
If we subtract 30 from 30, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 5

Step 5:
The number 5 fits into 8 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 8061.0
The remainder is 3 after subtracting 5 from 8.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 5

Advancing to step 6:
5 goes into 39 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 80617.0
Deduct 35 from 39 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 5

Moving on to step 7:
When dividing 44 by 5, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 806178.0
If we subtract 40 from 44, we get 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 5

Advancing to step 8:
5 goes into 47 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 8061789.0
The remainder is 2 after subtracting 45 from 47.
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 9:
20 divided by 5 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 8061789.4
If we take 20 away from 20, 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.

Advancing to step 10:
5 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8061789.4
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.

Let's proceed to step 11:
0 divided by 5 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8061789.4
If we take 0 away from 0, 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.

Our division results in 8061789.4 with a remaining 0.0.
