587840 ÷ 10 
We want to figure out the number of times 587840 can be divided by 10.

Moving on to step 1:
10 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 10

Going ahead to step 2:
10 goes into 58 5 times with a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 50 away from 58, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 10

Let's proceed to step 3:
The number 10 fits into 87 8 times, leaving a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtracting 80 from 87 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 10

Let's proceed to step 4:
If we divide 78 by 10, we get 7 and a remainder of 8.
The next digit of our result is 7. 
Result so far: 587.0
The remainder is 8 after subtracting 70 from 78.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 10

Let's proceed to step 5:
When dividing 84 by 10, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 5878.0
Subtract 80 from 84 to get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 10

Step 6:
10 can be fit into 40 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 58784.0
Subtracting 40 from 40 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 7:
0 divided by 10 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 58784.0
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:
When dividing 0 by 10, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 58784.0
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.

The final outcome is 58784.0, with a leftover of 0.0.
