We're dividing 12330240 by 630 
Our goal is to divide 12330240 by 630.

Going ahead to step 1:
The number 630 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 630

On to step 2:
The number 630 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 630

On to step 3:
630 can be fit into 123 0 times, resulting in a remainder of 123.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 123 after subtracting 0 from 123.
Take the next digit (3) from the dividend and append it to 123, then repeat: 1233 / 630

On to step 4:
630 can be fit into 1233 1 times, resulting in a remainder of 603.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 630 from 1233 to get 603.
Fetch the next digit (0) from the dividend, attach it to 603 and continue: 6030 / 630

Advancing to step 5:
6030 divided by 630 is 9 with a remainder of 360.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 5670 away from 6030, we end up with 360.
Fetch the next digit (2) from the dividend, attach it to 360 and continue: 3602 / 630

Let's proceed to step 6:
When dividing 3602 by 630, we get 5 with a remainder of 452.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtract 3150 from 3602 to get 452.
Include the next digit (4) from the dividend after 452, then repeat: 4524 / 630

Step 7:
630 can be fit into 4524 7 times, resulting in a remainder of 114.
Record the quotient 7 as the next digit in the result. 
Result so far: 1957.0
Subtract 4410 from 4524 to get 114.
Bring next digit (0) of the dividend behind the 114 and repeat the process: 1140 / 630

Advancing to step 8:
When dividing 1140 by 630, we get 1 with a remainder of 510.
Write down 1 as next digit of the result. 
Result so far: 19571.0
The remainder is 510 after subtracting 630 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Advancing to step 9:
5100 divided by 630 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 19571.8
Deduct 5040 from 5100 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 10:
When dividing 600 by 630, we get 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 19571.8
Deduct 0 from 600 and we're left with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 11:
630 goes into 6000 9 times with a remainder of 330.
Write down 9 as next digit of the result. 
Result so far: 19571.809
The remainder is 330 after subtracting 5670 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 12:
The number 630 fits into 3300 5 times, leaving a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 19571.8095
Deduct 3150 from 3300 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 13:
The number 630 fits into 1500 2 times, leaving a remainder of 240.
Write down 2 as next digit of the result. 
Result so far: 19571.80952
Deduct 1260 from 1500 and we're left with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 14:
2400 divided by 630 is 3 with a remainder of 510.
Write down 3 as next digit of the result. 
Result so far: 19571.809523
If we take 1890 away from 2400, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

Let's proceed to step 15:
When dividing 5100 by 630, we get 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 19571.8095238
Subtract 5040 from 5100 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 16:
600 divided by 630 is 0 with a remainder of 600.
The next digit of our result is 0. 
Result so far: 19571.8095238
The remainder is 600 after subtracting 0 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

The final outcome is 19571.8095238, with a leftover of 6e-07.
