We divide 859584 by 10
Let's see how many times 10 fits into 859584.

Advancing to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 10

Moving on to step 2:
If we divide 85 by 10, we get 8 and a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 80 from 85 leaves us with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 10

Let's proceed to step 3:
When dividing 59 by 10, we get 5 with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 85.0
Subtract 50 from 59 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 10

Moving on to step 4:
95 divided by 10 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 859.0
The remainder is 5 after subtracting 90 from 95.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 10

On to step 5:
10 goes into 58 5 times with a remainder of 8.
The number 5 becomes the next digit in our result. 
Result so far: 8595.0
The remainder is 8 after subtracting 50 from 58.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 10

Advancing to step 6:
10 can be fit into 84 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 85958.0
Deduct 80 from 84 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 10, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 85958.4
If we subtract 40 from 40, 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.

Let's proceed to step 8:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 85958.4
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.

Advancing to step 9:
The number 10 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 85958.4
Deduct 0 from 0 and we're left 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.

The final outcome is 85958.4, with a leftover of 0.0.
