We look at the division of 873584 by 10 
We want to figure out the number of times 873584 can be divided by 10.

Step 1:
8 divided by 10 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 10

On to step 2:
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: 8.0
If we take 80 away from 87, we end up with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 10

Going ahead to step 3:
The number 10 fits into 73 7 times, leaving a remainder of 3.
The next digit of our result is 7. 
Result so far: 87.0
Subtract 70 from 73 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 10

On to step 4:
If we divide 35 by 10, we get 3 and a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 873.0
Subtract 30 from 35 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 10

Going ahead to step 5:
10 can be fit into 58 5 times, resulting in a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 8735.0
If we take 50 away from 58, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 10

On to step 6:
When dividing 84 by 10, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 87358.0
Subtract 80 from 84 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
10 can be fit into 40 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 87358.4
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.

Step 8:
0 divided by 10 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 87358.4
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.

Advancing to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 87358.4
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.

The final outcome is 87358.4, with a leftover of 0.0.
