129504 divided by 43 
Let's see how many times 43 fits into 129504.

On to step 1:
1 divided by 43 is 0 with 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 43

Moving on to step 2:
43 goes into 12 0 times with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 43

Advancing to step 3:
If we divide 129 by 43, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 129 from 129 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 43

Moving on to step 4:
43 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 43

On to step 5:
50 divided by 43 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
Subtract 43 from 50 to get 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 43

Advancing to step 6:
43 goes into 74 1 times with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 3011.0
If we take 43 away from 74, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
43 can be fit into 310 7 times, resulting in a remainder of 9.
The next digit of our result is 7. 
Result so far: 3011.7
If we take 301 away from 310, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
When dividing 90 by 43, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 3011.72
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 3011.72
Deduct 0 from 40 and we're left 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 10:
400 divided by 43 is 9 with a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 3011.7209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 11:
When dividing 130 by 43, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3011.72093
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 12:
The number 43 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3011.72093
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 3011.7209302
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 14:
When dividing 140 by 43, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3011.72093023
Subtract 129 from 140 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 3011.72093023 with a remainder of 1.1e-08.
