Let's divide 857915 by 85
We want to figure out the number of times 857915 can be divided by 85.

Let's proceed to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 85

Let's proceed to step 2:
85 divided by 85 is 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 85 from 85 leaves us with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 85

Advancing to step 3:
When dividing 7 by 85, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 85

Step 4:
85 goes into 79 0 times with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 79 after subtracting 0 from 79.
Append the next digit (1) from the dividend to 79 and continue with: 791 / 85

Moving on to step 5:
85 goes into 791 9 times with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
If we take 765 away from 791, we end up with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 85

Moving on to step 6:
If we divide 265 by 85, we get 3 and a remainder of 10.
The next digit of our result is 3. 
Result so far: 10093.0
If we take 255 away from 265, 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.

Let's proceed to step 7:
100 divided by 85 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 10093.1
If we subtract 85 from 100, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 85, we get 1 with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10093.11
If we subtract 85 from 150, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

The quotient of the division is 10093.11, and the remainder is 0.065.
