We look at the division of 856705 by 90 
We want to figure out the number of times 856705 can be divided by 90.

Step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 90

On to step 2:
90 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Grab the next digit (6) from the dividend, add it to 85, then carry on: 856 / 90

Advancing to step 3:
When dividing 856 by 90, we get 9 with a remainder of 46.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 46 after subtracting 810 from 856.
Bring next digit (7) of the dividend behind the 46 and repeat the process: 467 / 90

On to step 4:
The number 90 fits into 467 5 times, leaving a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 95.0
The remainder is 17 after subtracting 450 from 467.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 90

Going ahead to step 5:
When dividing 170 by 90, we get 1 with a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 951.0
Subtracting 90 from 170 leaves us with 80.
Bring next digit (5) of the dividend behind the 80 and repeat the process: 805 / 90

Moving on to step 6:
If we divide 805 by 90, we get 8 and a remainder of 85.
Put 8 as the next digit of the answer. 
Result so far: 9518.0
The remainder is 85 after subtracting 720 from 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 7:
850 divided by 90 is 9 with a remainder of 40.
Write down 9 as next digit of the result. 
Result so far: 9518.9
Subtract 810 from 850 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
90 can be fit into 400 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 9518.94
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 9518.944
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 9518.944 with a remaining 0.004.
