859380 ÷ 9 
Our goal is to divide 859380 by 9.

Going ahead to step 1:
If we divide 8 by 9, we get 0 and 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 (5) from the dividend and append it to 8, then repeat: 85 / 9

Step 2:
9 goes into 85 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 81 from 85 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 9

Advancing to step 3:
The number 9 fits into 49 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 95.0
If we take 45 away from 49, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Advancing to step 4:
When dividing 43 by 9, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 954.0
The remainder is 7 after subtracting 36 from 43.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 9

Step 5:
The number 9 fits into 78 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 9548.0
Subtract 72 from 78 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 9

Advancing to step 6:
9 can be fit into 60 6 times, resulting in a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 95486.0
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
When dividing 60 by 9, we get 6 with a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 95486.6
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 9, we get 6 and a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 95486.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

After the division, we end up with 95486.66 and a remainder of 0.006.
