807630 divided by 51 
We're looking to find how many times 51 goes into 807630.

Advancing to step 1:
When dividing 8 by 51, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 51

Let's proceed to step 2:
The number 51 fits into 80 1 times, leaving a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 29 after subtracting 51 from 80.
Take the next digit (7) from the dividend and append it to 29, then repeat: 297 / 51

Step 3:
If we divide 297 by 51, we get 5 and a remainder of 42.
Use 5 as the next digit of our solution. 
Result so far: 15.0
If we subtract 255 from 297, we get 42.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 51

On to step 4:
51 can be fit into 426 8 times, resulting in a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 158.0
Subtracting 408 from 426 leaves us with 18.
Take the next digit (3) from the dividend and append it to 18, then repeat: 183 / 51

On to step 5:
If we divide 183 by 51, we get 3 and a remainder of 30.
Write down 3 as next digit of the result. 
Result so far: 1583.0
The remainder is 30 after subtracting 153 from 183.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 51

Step 6:
When dividing 300 by 51, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15835.0
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.

Moving on to step 7:
When dividing 450 by 51, we get 8 with a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 15835.8
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.

Let's proceed to step 8:
51 goes into 420 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 15835.88
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.

Our division results in 15835.88 with a remaining 0.012.
