We look at the division of 845904 by 27 
We're looking to find how many times 27 goes into 845904.

Let's proceed to step 1:
27 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 27

Let's proceed to step 2:
27 goes into 84 3 times with a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 81 from 84 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 27

On to step 3:
27 can be fit into 35 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtract 27 from 35 to get 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 27

Moving on to step 4:
If we divide 89 by 27, we get 3 and a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 313.0
If we take 81 away from 89, we end up with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 27

Let's proceed to step 5:
The number 27 fits into 80 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 3132.0
Subtract 54 from 80 to get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 27

On to step 6:
27 can be fit into 264 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 31329.0
The remainder is 21 after subtracting 243 from 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
The number 27 fits into 210 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 31329.7
Subtract 189 from 210 to get 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:
210 divided by 27 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 31329.77
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 outcome is 31329.77, with a leftover of 0.021.
