We look at the division of 858869 by 10 
Let's see how many times 10 fits into 858869.

Let's proceed to step 1:
If we divide 8 by 10, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 10

Moving on to step 2:
If we divide 85 by 10, we get 8 and a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 80 away from 85, we end up with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 10

On to step 3:
If we divide 58 by 10, we get 5 and a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 85.0
If we subtract 50 from 58, we get 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 10

Let's proceed to step 4:
10 can be fit into 88 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 858.0
The remainder is 8 after subtracting 80 from 88.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 10

Step 5:
The number 10 fits into 86 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 8588.0
Subtract 80 from 86 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 10

Going ahead to step 6:
When dividing 69 by 10, we get 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 85886.0
If we take 60 away from 69, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
10 can be fit into 90 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 85886.9
If we take 90 away from 90, 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.

Going ahead to step 8:
10 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 85886.9
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:
If we divide 0 by 10, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 85886.9
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.

The quotient of the division is 85886.9, and the remainder is 0.0.
