431820 ÷ 27 
We want to figure out the number of times 431820 can be divided by 27.

Step 1:
4 divided by 27 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 27

Let's proceed to step 2:
If we divide 43 by 27, we get 1 and a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 27 away from 43, we end up with 16.
Take the next digit (1) from the dividend and append it to 16, then repeat: 161 / 27

Step 3:
The number 27 fits into 161 5 times, leaving a remainder of 26.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 26 after subtracting 135 from 161.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 27

Moving on to step 4:
27 can be fit into 268 9 times, resulting in a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we take 243 away from 268, we end up with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 27

Advancing to step 5:
The number 27 fits into 252 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 1599.0
If we take 243 away from 252, we end up with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 27

On to step 6:
27 goes into 90 3 times with a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 15993.0
The remainder is 9 after subtracting 81 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
27 can be fit into 90 3 times, resulting in a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 15993.3
Subtracting 81 from 90 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
27 goes into 90 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 15993.33
If we take 81 away from 90, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 15993.33 with a remainder of 0.009.
