858913 ÷ 1 
We want to figure out the number of times 858913 can be divided by 1.

Moving on to step 1:
When dividing 8 by 1, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

On to step 2:
5 divided by 1 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 85.0
If we take 5 away from 5, we end up with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Let's proceed to step 3:
When dividing 8 by 1, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 858.0
If we take 8 away from 8, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 1

Let's proceed to step 4:
The number 1 fits into 9 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 8589.0
The remainder is 0 after subtracting 9 from 9.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 5:
If we divide 1 by 1, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 85891.0
The remainder is 0 after subtracting 1 from 1.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Step 6:
When dividing 3 by 1, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 858913.0
Deduct 3 from 3 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.

Moving on to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 858913.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 858913.0
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.

In conclusion, the division gives 858913.0 with a balance of 0.0.
