We look at the division of 402451 by 27 
We want to divide 402451 by 27.

Going ahead to step 1:
The number 27 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 27

Let's proceed to step 2:
If we divide 40 by 27, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 27 from 40 and we're left with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 27

Moving on to step 3:
132 divided by 27 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 14.0
If we subtract 108 from 132, we get 24.
Fetch the next digit (4) from the dividend, attach it to 24 and continue: 244 / 27

Advancing to step 4:
If we divide 244 by 27, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 149.0
If we subtract 243 from 244, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 27

Step 5:
The number 27 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 1490.0
Subtract 0 from 15 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 27

On to step 6:
27 can be fit into 151 5 times, resulting in a remainder of 16.
Record the quotient 5 as the next digit in the result. 
Result so far: 14905.0
Subtracting 135 from 151 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
If we divide 160 by 27, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 14905.5
If we subtract 135 from 160, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 8:
27 can be fit into 250 9 times, resulting in a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 14905.59
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 9:
27 can be fit into 70 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 14905.592
Subtract 54 from 70 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
The number 27 fits into 160 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 14905.5925
Subtract 135 from 160 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 11:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 14905.59259
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
The number 27 fits into 70 2 times, leaving a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 14905.592592
If we subtract 54 from 70, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 27 fits into 160 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 14905.5925925
Subtract 135 from 160 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
If we divide 250 by 27, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 14905.59259259
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 14905.59259259 with a remainder of 7e-09.
