360804 divided by 51 
Let's see how many times 51 fits into 360804.

Moving on to step 1:
51 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 51

Advancing to step 2:
When dividing 36 by 51, we get 0 with a remainder of 36.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 36 leaves us with 36.
Take the next digit (0) from the dividend and append it to 36, then repeat: 360 / 51

Going ahead to step 3:
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: 7.0
If we subtract 357 from 360, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 51

On to step 4:
38 divided by 51 is 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 51

Going ahead to step 5:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 707.0
Subtract 357 from 380 to get 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 51

Step 6:
51 can be fit into 234 4 times, resulting in a remainder of 30.
The next digit of our result is 4. 
Result so far: 7074.0
Subtracting 204 from 234 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
If we divide 300 by 51, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 7074.5
Deduct 255 from 300 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 8:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 7074.58
Subtracting 408 from 450 leaves us 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.

Going ahead to step 9:
420 divided by 51 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 7074.588
The remainder is 12 after subtracting 408 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 7074.588, and the remainder is 0.0012.
