Let's divide 270234 by 51
We want to figure out the number of times 270234 can be divided by 51.

On to step 1:
51 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 51

Step 2:
The number 51 fits into 27 0 times, leaving a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 51

Going ahead to step 3:
51 goes into 270 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 255 from 270, we get 15.
Take the next digit (2) from the dividend and append it to 15, then repeat: 152 / 51

Let's proceed to step 4:
51 goes into 152 2 times with a remainder of 50.
Put 2 as the next digit of the answer. 
Result so far: 52.0
If we take 102 away from 152, we end up with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 51

Step 5:
If we divide 503 by 51, we get 9 and a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 529.0
If we take 459 away from 503, we end up with 44.
Take the next digit (4) from the dividend and append it to 44, then repeat: 444 / 51

Moving on to step 6:
The number 51 fits into 444 8 times, leaving a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 5298.0
If we take 408 away from 444, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 7:
360 divided by 51 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 5298.7
Subtract 357 from 360 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
51 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 5298.7
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
300 divided by 51 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 5298.705
Subtract 255 from 300 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 10:
The number 51 fits into 450 8 times, leaving a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 5298.7058
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 11:
If we divide 420 by 51, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 5298.70588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5298.70588 with a remainder of 1.2e-05.
