We divide 857859 by 27
We want to figure out the number of times 857859 can be divided by 27.

Advancing to step 1:
The number 27 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 27

Advancing to step 2:
The number 27 fits into 85 3 times, leaving a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 81 away from 85, we end up with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 27

Advancing to step 3:
When dividing 47 by 27, we get 1 with a remainder of 20.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Deduct 27 from 47 and we're left with 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 27

Let's proceed to step 4:
208 divided by 27 is 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 317.0
Subtract 189 from 208 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 27

Let's proceed to step 5:
When dividing 195 by 27, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 3177.0
Subtract 189 from 195 to get 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 27

Let's proceed to step 6:
27 goes into 69 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 31772.0
Subtract 54 from 69 to 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.

Going ahead to step 7:
If we divide 150 by 27, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 31772.5
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
If we divide 150 by 27, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 31772.55
If we subtract 135 from 150, 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.

After the division, we end up with 31772.55 and a remainder of 0.015.
