Let's divide 630353 by 12
Let's see how many times 12 fits into 630353.

Moving on to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 12

On to step 2:
12 can be fit into 63 5 times, resulting in a remainder of 3.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 60 from 63, we get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 12

On to step 3:
If we divide 30 by 12, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 24 from 30 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 12

Moving on to step 4:
63 divided by 12 is 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 525.0
If we take 60 away from 63, we end up with 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 12

Moving on to step 5:
When dividing 35 by 12, we get 2 with a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 5252.0
If we subtract 24 from 35, we get 11.
Append the next digit (3) from the dividend to 11 and continue with: 113 / 12

Advancing to step 6:
12 can be fit into 113 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 52529.0
Deduct 108 from 113 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
The number 12 fits into 50 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 52529.4
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 52529.41
Subtracting 12 from 20 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 52529.416
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 52529.4166
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 52529.4166 and a remainder of 8e-05.
