We divide 510597 by 51
Our goal is to divide 510597 by 51.

Going ahead to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 51

Moving on to step 2:
If we divide 51 by 51, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 51 and we're left with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 51

Let's proceed to step 3:
0 divided by 51 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 51

Advancing to step 4:
5 divided by 51 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 100.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 51

Moving on to step 5:
51 goes into 59 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1001.0
If we take 51 away from 59, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 51

Step 6:
The number 51 fits into 87 1 times, leaving a remainder of 36.
The next digit of our result is 1. 
Result so far: 10011.0
If we subtract 51 from 87, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
The number 51 fits into 360 7 times, leaving a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 10011.7
If we take 357 away from 360, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
The number 51 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 10011.7
Subtract 0 from 30 to 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.

Going ahead to step 9:
The number 51 fits into 300 5 times, leaving a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 10011.705
If we subtract 255 from 300, we 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:
450 divided by 51 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 10011.7058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
420 divided by 51 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 10011.70588
Subtracting 408 from 420 leaves us with 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 10011.70588 with a remainder of 1.2e-05.
