16210209 divided by 630 
We want to figure out the number of times 16210209 can be divided by 630.

Advancing to step 1:
630 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 630

Moving on to step 2:
630 can be fit into 16 0 times, resulting in a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 16 to get 16.
Append the next digit (2) from the dividend to 16 and continue with: 162 / 630

Advancing to step 3:
630 can be fit into 162 0 times, resulting in a remainder of 162.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 162 after subtracting 0 from 162.
Take the next digit (1) from the dividend and append it to 162, then repeat: 1621 / 630

Moving on to step 4:
If we divide 1621 by 630, we get 2 and a remainder of 361.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 1260 from 1621 and we're left with 361.
Take the next digit (0) from the dividend and append it to 361, then repeat: 3610 / 630

On to step 5:
630 can be fit into 3610 5 times, resulting in a remainder of 460.
The next digit of our result is 5. 
Result so far: 25.0
If we take 3150 away from 3610, we end up with 460.
Fetch the next digit (2) from the dividend, attach it to 460 and continue: 4602 / 630

Going ahead to step 6:
4602 divided by 630 is 7 with a remainder of 192.
Use 7 as the next digit of our solution. 
Result so far: 257.0
The remainder is 192 after subtracting 4410 from 4602.
Bring next digit (0) of the dividend behind the 192 and repeat the process: 1920 / 630

Moving on to step 7:
If we divide 1920 by 630, we get 3 and a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 2573.0
Subtract 1890 from 1920 to get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 630

Advancing to step 8:
If we divide 309 by 630, we get 0 and a remainder of 309.
Record the quotient 0 as the next digit in the result. 
Result so far: 25730.0
Subtracting 0 from 309 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 9:
The number 630 fits into 3090 4 times, leaving a remainder of 570.
The next digit of our result is 4. 
Result so far: 25730.4
If we subtract 2520 from 3090, we get 570.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Going ahead to step 10:
When dividing 5700 by 630, we get 9 with a remainder of 30.
The next digit of our result is 9. 
Result so far: 25730.49
The remainder is 30 after subtracting 5670 from 5700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
630 can be fit into 300 0 times, resulting in a remainder of 300.
The next digit of our result is 0. 
Result so far: 25730.49
The remainder is 300 after subtracting 0 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 12:
The number 630 fits into 3000 4 times, leaving a remainder of 480.
Put 4 as the next digit of the answer. 
Result so far: 25730.4904
Subtract 2520 from 3000 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
If we divide 4800 by 630, we get 7 and a remainder of 390.
Write down 7 as next digit of the result. 
Result so far: 25730.49047
Subtracting 4410 from 4800 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 14:
3900 divided by 630 is 6 with a remainder of 120.
Record the quotient 6 as the next digit in the result. 
Result so far: 25730.490476
The remainder is 120 after subtracting 3780 from 3900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
630 can be fit into 1200 1 times, resulting in a remainder of 570.
The number 1 becomes the next digit in our result. 
Result so far: 25730.4904761
The remainder is 570 after subtracting 630 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

Advancing to step 16:
5700 divided by 630 is 9 with a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 25730.49047619
Subtracting 5670 from 5700 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 25730.49047619 with a balance of 3e-08.
