16209 ÷ 63 
We want to divide 16209 by 63.

Advancing to step 1:
63 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 63

Going ahead to step 2:
63 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 63

Moving on to step 3:
63 can be fit into 162 2 times, resulting in a remainder of 36.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 126 from 162 to get 36.
Grab the next digit (0) from the dividend, add it to 36, then carry on: 360 / 63

Let's proceed to step 4:
If we divide 360 by 63, we get 5 and a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 315 away from 360, we end up with 45.
Grab the next digit (9) from the dividend, add it to 45, then carry on: 459 / 63

Going ahead to step 5:
63 goes into 459 7 times with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 257.0
Deduct 441 from 459 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 6:
180 divided by 63 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 257.2
The remainder is 54 after subtracting 126 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
When dividing 540 by 63, we get 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 257.28
If we take 504 away from 540, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 8:
63 can be fit into 360 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 257.285
Deduct 315 from 360 and we're left with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
When dividing 450 by 63, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 257.2857
If we subtract 441 from 450, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 10:
63 goes into 90 1 times with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 257.28571
If we take 63 away from 90, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Moving on to step 11:
63 goes into 270 4 times with a remainder of 18.
The next digit of our result is 4. 
Result so far: 257.285714
Subtracting 252 from 270 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 63 fits into 180 2 times, leaving a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 257.2857142
Subtracting 126 from 180 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
540 divided by 63 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 257.28571428
Deduct 504 from 540 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 257.28571428 with a balance of 3.6e-08.
