We're dividing 428389 by 27 
We want to divide 428389 by 27.

Going ahead to step 1:
27 can be fit into 4 0 times, resulting in 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.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 27

Moving on to step 2:
The number 27 fits into 42 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 27 away from 42, we end up with 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 27

Moving on to step 3:
27 can be fit into 158 5 times, resulting in a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 135 from 158 leaves us with 23.
Append the next digit (3) from the dividend to 23 and continue with: 233 / 27

On to step 4:
27 goes into 233 8 times with a remainder of 17.
Write down 8 as next digit of the result. 
Result so far: 158.0
Deduct 216 from 233 and we're left with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 27

Step 5:
The number 27 fits into 178 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 1586.0
If we subtract 162 from 178, we get 16.
Include the next digit (9) from the dividend after 16, then repeat: 169 / 27

Let's proceed to step 6:
When dividing 169 by 27, we get 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 15866.0
The remainder is 7 after subtracting 162 from 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 27 is 2 with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 15866.2
Deduct 54 from 70 and we're left 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.

Step 8:
27 goes into 160 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 15866.25
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
27 goes into 250 9 times with a remainder of 7.
Write down 9 as next digit of the result. 
Result so far: 15866.259
The remainder is 7 after subtracting 243 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 27 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 15866.2592
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.

Let's proceed to step 11:
27 goes into 160 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15866.25925
Subtracting 135 from 160 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 12:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 15866.259259
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.

Let's proceed to step 13:
27 goes into 70 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 15866.2592592
If we take 54 away from 70, we end up 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.

Step 14:
27 goes into 160 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 15866.25925925
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.

The final result is 15866.25925925 with a remainder of 2.5e-08.
