Let's divide 129009 by 52
We want to figure out the number of times 129009 can be divided by 52.

Going ahead to step 1:
52 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 52

Moving on to step 2:
If we divide 12 by 52, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 52

Advancing to step 3:
52 can be fit into 129 2 times, resulting in a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 104 from 129 leaves us with 25.
Append the next digit (0) from the dividend to 25 and continue with: 250 / 52

Advancing to step 4:
The number 52 fits into 250 4 times, leaving a remainder of 42.
The next digit of our result is 4. 
Result so far: 24.0
The remainder is 42 after subtracting 208 from 250.
Bring next digit (0) of the dividend behind the 42 and repeat the process: 420 / 52

Advancing to step 5:
If we divide 420 by 52, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 248.0
Subtract 416 from 420 to get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 52

Let's proceed to step 6:
52 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 2480.0
Subtract 0 from 49 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 7:
52 can be fit into 490 9 times, resulting in a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 2480.9
Deduct 468 from 490 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 8:
52 can be fit into 220 4 times, resulting in a remainder of 12.
The next digit of our result is 4. 
Result so far: 2480.94
If we take 208 away from 220, we end up 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.

Going ahead to step 9:
120 divided by 52 is 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2480.942
Subtracting 104 from 120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
52 can be fit into 160 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 2480.9423
Deduct 156 from 160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
52 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2480.9423
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
If we divide 400 by 52, we get 7 and a remainder of 36.
The next digit of our result is 7. 
Result so far: 2480.942307
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 2480.9423076
If we take 312 away from 360, 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.

Going ahead to step 14:
480 divided by 52 is 9 with a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 2480.94230769
Subtracting 468 from 480 leaves us 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.

Our division results in 2480.94230769 with a remaining 1.2e-08.
