We divide 129009 by 63
We're looking to find how many times 63 goes into 129009.

Step 1:
The number 63 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 63

Moving on to step 2:
63 can be fit into 12 0 times, resulting in 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.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 63

On to step 3:
129 divided by 63 is 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 126 from 129 leaves us with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 63

Advancing to step 4:
63 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we subtract 0 from 30, we get 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 63

Step 5:
63 goes into 300 4 times with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we take 252 away from 300, we end up with 48.
Fetch the next digit (9) from the dividend, attach it to 48 and continue: 489 / 63

Going ahead to step 6:
The number 63 fits into 489 7 times, leaving a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 2047.0
If we subtract 441 from 489, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 7:
480 divided by 63 is 7 with a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 2047.7
Subtract 441 from 480 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
If we divide 390 by 63, we get 6 and a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2047.76
If we subtract 378 from 390, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
63 can be fit into 120 1 times, resulting in a remainder of 57.
Use 1 as the next digit of our solution. 
Result so far: 2047.761
Subtracting 63 from 120 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
63 can be fit into 570 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 2047.7619
If we take 567 away from 570, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 11:
The number 63 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 2047.7619
If we take 0 away from 30, we end up 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.

Advancing to step 12:
When dividing 300 by 63, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 2047.761904
If we take 252 away from 300, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
The number 63 fits into 480 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 2047.7619047
The remainder is 39 after subtracting 441 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 14:
63 goes into 390 6 times with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 2047.76190476
Deduct 378 from 390 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 2047.76190476 and a remainder of 1.2e-08.
