521387 ÷ 27 
Our goal is to divide 521387 by 27.

Let's proceed to step 1:
If we divide 5 by 27, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 27

Step 2:
52 divided by 27 is 1 with a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 27 from 52 leaves us with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 27

Moving on to step 3:
If we divide 251 by 27, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 8 after subtracting 243 from 251.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 27

Going ahead to step 4:
27 goes into 83 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 193.0
Subtracting 81 from 83 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 27

Let's proceed to step 5:
If we divide 28 by 27, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1931.0
Deduct 27 from 28 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 27

Let's proceed to step 6:
When dividing 17 by 27, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 19310.0
Subtracting 0 from 17 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.

Step 7:
When dividing 170 by 27, we get 6 with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19310.6
If we take 162 away from 170, we end up 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:
When dividing 80 by 27, we get 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 19310.62
If we take 54 away from 80, we end up 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.

Going ahead to step 9:
The number 27 fits into 260 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 19310.629
Deduct 243 from 260 and we're left 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:
The number 27 fits into 170 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 19310.6296
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
80 divided by 27 is 2 with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 19310.62962
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:
If we divide 260 by 27, we get 9 and a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19310.629629
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.

Let's proceed to step 13:
27 goes into 170 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 19310.6296296
If we take 162 away from 170, we end up 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.

Let's proceed to step 14:
27 goes into 80 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 19310.62962962
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.

Our division results in 19310.62962962 with a remaining 2.6e-08.
