The remainder is 4 after subtracting 0 from 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 129

Step 2:
If we divide 44 by 129, we get 0 and a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 44 after subtracting 0 from 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 129

Step 3:
The number 129 fits into 443 3 times, leaving a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 387 from 443 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 129

Advancing to step 4:
The number 129 fits into 566 4 times, leaving a remainder of 50.
The next digit of our result is 4. 
Result so far: 34.0
Subtract 516 from 566 to get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 129

On to step 5:
If we divide 501 by 129, we get 3 and a remainder of 114.
The next digit of our result is 3. 
Result so far: 343.0
Subtracting 387 from 501 leaves us with 114.
Fetch the next digit (9) from the dividend, attach it to 114 and continue: 1149 / 129

On to step 6:
When dividing 1149 by 129, we get 8 with a remainder of 117.
The next digit of our result is 8. 
Result so far: 3438.0
Subtracting 1032 from 1149 leaves us with 117.
Grab the next digit (2) from the dividend, add it to 117, then carry on: 1172 / 129

Let's proceed to step 7:
129 can be fit into 1172 9 times, resulting in a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 34389.0
If we take 1161 away from 1172, we end up with 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 129

Advancing to step 8:
129 goes into 112 0 times with a remainder of 112.
The number 0 becomes the next digit in our result. 
Result so far: 343890.0
Subtract 0 from 112 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
1120 divided by 129 is 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 343890.8
The remainder is 88 after subtracting 1032 from 1120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 10:
129 goes into 880 6 times with a remainder of 106.
The next digit of our result is 6. 
Result so far: 343890.86
Subtracting 774 from 880 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 11:
The number 129 fits into 1060 8 times, leaving a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 343890.868
The remainder is 28 after subtracting 1032 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
If we divide 280 by 129, we get 2 and a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 343890.8682
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
129 goes into 220 1 times with a remainder of 91.
The number 1 becomes the next digit in our result. 
Result so far: 343890.86821
Subtracting 129 from 220 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Moving on to step 14:
129 goes into 910 7 times with a remainder of 7.
The next digit of our result is 7. 
Result so far: 343890.868217
Subtracting 903 from 910 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 15:
129 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 343890.868217
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 16:
129 can be fit into 700 5 times, resulting in a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 343890.86821705
Subtracting 645 from 700 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Our division results in 343890.86821705 with a remaining 5.5e-08.
