We're dividing 18309953 by 630 
We want to divide 18309953 by 630.

Let's proceed to step 1:
630 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 630

Let's proceed to step 2:
When dividing 18 by 630, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 630

Step 3:
If we divide 183 by 630, we get 0 and a remainder of 183.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 183 after subtracting 0 from 183.
Grab the next digit (0) from the dividend, add it to 183, then carry on: 1830 / 630

Advancing to step 4:
630 goes into 1830 2 times with a remainder of 570.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 1260 from 1830 leaves us with 570.
Bring next digit (9) of the dividend behind the 570 and repeat the process: 5709 / 630

Advancing to step 5:
The number 630 fits into 5709 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 39 after subtracting 5670 from 5709.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 630

Step 6:
630 goes into 399 0 times with a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 290.0
Subtracting 0 from 399 leaves us with 399.
Take the next digit (5) from the dividend and append it to 399, then repeat: 3995 / 630

Moving on to step 7:
630 goes into 3995 6 times with a remainder of 215.
Use 6 as the next digit of our solution. 
Result so far: 2906.0
Subtract 3780 from 3995 to get 215.
Append the next digit (3) from the dividend to 215 and continue with: 2153 / 630

Moving on to step 8:
If we divide 2153 by 630, we get 3 and a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 29063.0
If we take 1890 away from 2153, we end up with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

On to step 9:
The number 630 fits into 2630 4 times, leaving a remainder of 110.
Write down 4 as next digit of the result. 
Result so far: 29063.4
The remainder is 110 after subtracting 2520 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 10:
The number 630 fits into 1100 1 times, leaving a remainder of 470.
Record the quotient 1 as the next digit in the result. 
Result so far: 29063.41
Deduct 630 from 1100 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 11:
4700 divided by 630 is 7 with a remainder of 290.
Record the quotient 7 as the next digit in the result. 
Result so far: 29063.417
Subtract 4410 from 4700 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Advancing to step 12:
630 goes into 2900 4 times with a remainder of 380.
Put 4 as the next digit of the answer. 
Result so far: 29063.4174
Subtract 2520 from 2900 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 13:
The number 630 fits into 3800 6 times, leaving a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 29063.41746
If we take 3780 away from 3800, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 630, we get 0 and a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 29063.41746
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Let's proceed to step 15:
630 goes into 2000 3 times with a remainder of 110.
Put 3 as the next digit of the answer. 
Result so far: 29063.4174603
Subtract 1890 from 2000 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
If we divide 1100 by 630, we get 1 and a remainder of 470.
The next digit of our result is 1. 
Result so far: 29063.41746031
Subtract 630 from 1100 to get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

In conclusion, the division gives 29063.41746031 with a balance of 4.7e-07.
