We look at the division of 853437 by 27 
Let's see how many times 27 fits into 853437.

On to step 1:
8 divided by 27 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 27

Let's proceed to step 2:
85 divided by 27 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 81 from 85 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 27

Let's proceed to step 3:
27 goes into 43 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 31.0
If we take 27 away from 43, we end up with 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 27

Advancing to step 4:
When dividing 164 by 27, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 316.0
If we take 162 away from 164, we end up with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 27

Moving on to step 5:
27 goes into 23 0 times with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 3160.0
Subtracting 0 from 23 leaves us with 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 27

Going ahead to step 6:
27 goes into 237 8 times with a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 31608.0
Deduct 216 from 237 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
210 divided by 27 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 31608.7
Subtracting 189 from 210 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
When dividing 210 by 27, we get 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 31608.77
Deduct 189 from 210 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 31608.77 with a remainder of 0.021.
