We're dividing 811325 by 51 
Let's see how many times 51 fits into 811325.

On to step 1:
8 divided by 51 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 51

Step 2:
51 can be fit into 81 1 times, resulting in a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 51 away from 81, we end up with 30.
Append the next digit (1) from the dividend to 30 and continue with: 301 / 51

Step 3:
51 goes into 301 5 times with a remainder of 46.
The next digit of our result is 5. 
Result so far: 15.0
Subtract 255 from 301 to get 46.
Include the next digit (3) from the dividend after 46, then repeat: 463 / 51

On to step 4:
When dividing 463 by 51, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we take 459 away from 463, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 51

Let's proceed to step 5:
When dividing 42 by 51, we get 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 1590.0
Subtract 0 from 42 to get 42.
Append the next digit (5) from the dividend to 42 and continue with: 425 / 51

Step 6:
51 goes into 425 8 times with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 15908.0
If we subtract 408 from 425, 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:
When dividing 170 by 51, we get 3 with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 15908.3
Deduct 153 from 170 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.

Advancing to step 8:
The number 51 fits into 170 3 times, leaving a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 15908.33
The remainder is 17 after subtracting 153 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 15908.33 with a remainder of 0.017.
