We're dividing 4055319 by 129 
We want to divide 4055319 by 129.

Moving on to step 1:
129 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 129

Going ahead to step 2:
If we divide 40 by 129, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 129

Moving on to step 3:
When dividing 405 by 129, we get 3 with a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 387 from 405 leaves us with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 129

On to step 4:
The number 129 fits into 185 1 times, leaving a remainder of 56.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 129 from 185 leaves us with 56.
Grab the next digit (3) from the dividend, add it to 56, then carry on: 563 / 129

On to step 5:
When dividing 563 by 129, we get 4 with a remainder of 47.
The next digit of our result is 4. 
Result so far: 314.0
If we subtract 516 from 563, we get 47.
Grab the next digit (1) from the dividend, add it to 47, then carry on: 471 / 129

Moving on to step 6:
129 goes into 471 3 times with a remainder of 84.
The next digit of our result is 3. 
Result so far: 3143.0
If we subtract 387 from 471, we get 84.
Include the next digit (9) from the dividend after 84, then repeat: 849 / 129

Step 7:
If we divide 849 by 129, we get 6 and a remainder of 75.
Write down 6 as next digit of the result. 
Result so far: 31436.0
The remainder is 75 after subtracting 774 from 849.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 8:
129 goes into 750 5 times with a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 31436.5
If we take 645 away from 750, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 9:
When dividing 1050 by 129, we get 8 with a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 31436.58
Deduct 1032 from 1050 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.

Let's proceed to step 10:
The number 129 fits into 180 1 times, leaving a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 31436.581
The remainder is 51 after subtracting 129 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
The number 129 fits into 510 3 times, leaving a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 31436.5813
Subtracting 387 from 510 leaves us with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Going ahead to step 12:
129 goes into 1230 9 times with a remainder of 69.
Write down 9 as next digit of the result. 
Result so far: 31436.58139
The remainder is 69 after subtracting 1161 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 13:
129 goes into 690 5 times with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 31436.581395
If we take 645 away from 690, we end up 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.

Moving on to step 14:
129 goes into 450 3 times with a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 31436.5813953
If we subtract 387 from 450, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 15:
The number 129 fits into 630 4 times, leaving a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 31436.58139534
The remainder is 114 after subtracting 516 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

After the division, we end up with 31436.58139534 and a remainder of 1.14e-07.
