51551831 ÷ 27 
Our goal is to divide 51551831 by 27.

Advancing to step 1:
If we divide 5 by 27, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 27

Moving on to step 2:
When dividing 51 by 27, we get 1 with a remainder of 24.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 27 from 51 and we're left with 24.
Include the next digit (5) from the dividend after 24, then repeat: 245 / 27

Step 3:
If we divide 245 by 27, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we take 243 away from 245, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 27

Let's proceed to step 4:
If we divide 25 by 27, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 190.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (1) from the dividend after 25, then repeat: 251 / 27

On to step 5:
The number 27 fits into 251 9 times, leaving a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 1909.0
Subtracting 243 from 251 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 27

Step 6:
27 goes into 88 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 19093.0
Deduct 81 from 88 and we're left with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 27

Step 7:
73 divided by 27 is 2 with a remainder of 19.
Use 2 as the next digit of our solution. 
Result so far: 190932.0
If we subtract 54 from 73, we get 19.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 27

Let's proceed to step 8:
The number 27 fits into 191 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 1909327.0
The remainder is 2 after subtracting 189 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 9:
20 divided by 27 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1909327.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
27 goes into 200 7 times with a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 1909327.07
Subtracting 189 from 200 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
The number 27 fits into 110 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1909327.074
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 12:
27 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1909327.074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
If we divide 200 by 27, we get 7 and a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 1909327.07407
If we take 189 away from 200, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 14:
110 divided by 27 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 1909327.074074
Deduct 108 from 110 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 15:
27 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1909327.074074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
27 can be fit into 200 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 1909327.07407407
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 1909327.07407407 with a remainder of 1.1e-08.
