15389 ÷ 27 
We're looking to find how many times 27 goes into 15389.

Advancing to step 1:
The number 27 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 27

Going ahead to step 2:
If we divide 15 by 27, we get 0 and a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 27

Moving on to step 3:
If we divide 153 by 27, we get 5 and a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 18 after subtracting 135 from 153.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 27

On to step 4:
When dividing 188 by 27, we get 6 with a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 56.0
Subtract 162 from 188 to get 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 27

Going ahead to step 5:
When dividing 269 by 27, we get 9 with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 569.0
Subtracting 243 from 269 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 6:
27 goes into 260 9 times with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 569.9
If we subtract 243 from 260, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
27 goes into 170 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 569.96
Subtracting 162 from 170 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
If we divide 80 by 27, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 569.962
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
If we divide 260 by 27, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 569.9629
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
When dividing 170 by 27, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 569.96296
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
If we divide 80 by 27, we get 2 and a remainder of 26.
Write down 2 as next digit of the result. 
Result so far: 569.962962
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 12:
260 divided by 27 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 569.9629629
If we take 243 away from 260, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 13:
When dividing 170 by 27, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 569.96296296
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 569.96296296 and a remainder of 8e-09.
