We divide 630873 by 12
We want to divide 630873 by 12.

On to step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 12

Advancing to step 2:
The number 12 fits into 63 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 60 from 63 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Let's proceed to step 3:
The number 12 fits into 30 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we take 24 away from 30, we end up with 6.
Bring next digit (8) of the dividend behind the 6 and repeat the process: 68 / 12

Step 4:
The number 12 fits into 68 5 times, leaving a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 525.0
Subtracting 60 from 68 leaves us with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 12

Let's proceed to step 5:
When dividing 87 by 12, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 5257.0
Subtract 84 from 87 to get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Let's proceed to step 6:
12 goes into 33 2 times with a remainder of 9.
The next digit of our result is 2. 
Result so far: 52572.0
Subtract 24 from 33 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 52572.7
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 52572.75
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52572.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 52572.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 52572.75, with a leftover of 0.0.
