We look at the division of 858711 by 85 
We're looking to find how many times 85 goes into 858711.

On to step 1:
85 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 85

Advancing to step 2:
85 can be fit into 85 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 85 from 85, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 85

On to step 3:
8 divided by 85 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 85

Step 4:
When dividing 87 by 85, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 101.0
If we take 85 away from 87, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 85

Step 5:
85 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 1010.0
The remainder is 21 after subtracting 0 from 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 85

Going ahead to step 6:
When dividing 211 by 85, we get 2 with a remainder of 41.
Use 2 as the next digit of our solution. 
Result so far: 10102.0
Deduct 170 from 211 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
If we divide 410 by 85, we get 4 and a remainder of 70.
The number 4 becomes the next digit in our result. 
Result so far: 10102.4
If we take 340 away from 410, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
85 goes into 700 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 10102.48
Subtracting 680 from 700 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
85 can be fit into 200 2 times, resulting in a remainder of 30.
The next digit of our result is 2. 
Result so far: 10102.482
Subtracting 170 from 200 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
85 can be fit into 300 3 times, resulting in a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 10102.4823
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 11:
If we divide 450 by 85, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10102.48235
Deduct 425 from 450 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 12:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 10102.482352
The remainder is 80 after subtracting 170 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 13:
800 divided by 85 is 9 with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 10102.4823529
Deduct 765 from 800 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 14:
When dividing 350 by 85, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 10102.48235294
If we take 340 away from 350, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10102.48235294, with a leftover of 1e-08.
