We look at the division of 12934142 by 630 
Let's see how many times 630 fits into 12934142.

Advancing to step 1:
1 divided by 630 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 630

On to step 2:
630 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 630

Let's proceed to step 3:
When dividing 129 by 630, we get 0 with a remainder of 129.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 129 after subtracting 0 from 129.
Fetch the next digit (3) from the dividend, attach it to 129 and continue: 1293 / 630

Moving on to step 4:
When dividing 1293 by 630, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 1260 from 1293, we get 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 630

Advancing to step 5:
When dividing 334 by 630, we get 0 with a remainder of 334.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 334, we get 334.
Include the next digit (1) from the dividend after 334, then repeat: 3341 / 630

Advancing to step 6:
The number 630 fits into 3341 5 times, leaving a remainder of 191.
Use 5 as the next digit of our solution. 
Result so far: 205.0
Subtracting 3150 from 3341 leaves us with 191.
Append the next digit (4) from the dividend to 191 and continue with: 1914 / 630

On to step 7:
1914 divided by 630 is 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 2053.0
Deduct 1890 from 1914 and we're left with 24.
Grab the next digit (2) from the dividend, add it to 24, then carry on: 242 / 630

Going ahead to step 8:
630 goes into 242 0 times with a remainder of 242.
The number 0 becomes the next digit in our result. 
Result so far: 20530.0
The remainder is 242 after subtracting 0 from 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 9:
When dividing 2420 by 630, we get 3 with a remainder of 530.
Use 3 as the next digit of our solution. 
Result so far: 20530.3
If we subtract 1890 from 2420, we get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Going ahead to step 10:
The number 630 fits into 5300 8 times, leaving a remainder of 260.
The next digit of our result is 8. 
Result so far: 20530.38
If we take 5040 away from 5300, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 11:
The number 630 fits into 2600 4 times, leaving a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 20530.384
If we take 2520 away from 2600, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 12:
The number 630 fits into 800 1 times, leaving a remainder of 170.
Put 1 as the next digit of the answer. 
Result so far: 20530.3841
If we take 630 away from 800, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 13:
630 can be fit into 1700 2 times, resulting in a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 20530.38412
If we subtract 1260 from 1700, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Step 14:
4400 divided by 630 is 6 with a remainder of 620.
Use 6 as the next digit of our solution. 
Result so far: 20530.384126
Subtracting 3780 from 4400 leaves us with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 15:
630 goes into 6200 9 times with a remainder of 530.
Record the quotient 9 as the next digit in the result. 
Result so far: 20530.3841269
Deduct 5670 from 6200 and we're left with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Moving on to step 16:
If we divide 5300 by 630, we get 8 and a remainder of 260.
The next digit of our result is 8. 
Result so far: 20530.38412698
Deduct 5040 from 5300 and we're left with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

The quotient of the division is 20530.38412698, and the remainder is 2.6e-07.
