We look at the division of 50050315 by 129 
We're looking to find how many times 129 goes into 50050315.

Let's proceed to step 1:
129 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 129

Going ahead to step 2:
50 divided by 129 is 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 50 after subtracting 0 from 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 129

Moving on to step 3:
If we divide 500 by 129, we get 3 and a remainder of 113.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 387 from 500 to get 113.
Bring next digit (5) of the dividend behind the 113 and repeat the process: 1135 / 129

On to step 4:
If we divide 1135 by 129, we get 8 and a remainder of 103.
Put 8 as the next digit of the answer. 
Result so far: 38.0
The remainder is 103 after subtracting 1032 from 1135.
Fetch the next digit (0) from the dividend, attach it to 103 and continue: 1030 / 129

Advancing to step 5:
The number 129 fits into 1030 7 times, leaving a remainder of 127.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Subtracting 903 from 1030 leaves us with 127.
Append the next digit (3) from the dividend to 127 and continue with: 1273 / 129

Step 6:
1273 divided by 129 is 9 with a remainder of 112.
Put 9 as the next digit of the answer. 
Result so far: 3879.0
If we take 1161 away from 1273, we end up with 112.
Append the next digit (1) from the dividend to 112 and continue with: 1121 / 129

Let's proceed to step 7:
129 goes into 1121 8 times with a remainder of 89.
Put 8 as the next digit of the answer. 
Result so far: 38798.0
The remainder is 89 after subtracting 1032 from 1121.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 129

Step 8:
895 divided by 129 is 6 with a remainder of 121.
The number 6 becomes the next digit in our result. 
Result so far: 387986.0
Subtracting 774 from 895 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
1210 divided by 129 is 9 with a remainder of 49.
The next digit of our result is 9. 
Result so far: 387986.9
If we subtract 1161 from 1210, we 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.

Advancing to step 10:
490 divided by 129 is 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 387986.93
Subtracting 387 from 490 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 11:
When dividing 1030 by 129, we get 7 with a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 387986.937
Subtracting 903 from 1030 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Advancing to step 12:
129 goes into 1270 9 times with a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 387986.9379
If we take 1161 away from 1270, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Step 13:
129 can be fit into 1090 8 times, resulting in a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 387986.93798
Subtracting 1032 from 1090 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
580 divided by 129 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 387986.937984
Deduct 516 from 580 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 15:
129 goes into 640 4 times with a remainder of 124.
The next digit of our result is 4. 
Result so far: 387986.9379844
If we take 516 away from 640, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final result is 387986.9379844 with a remainder of 1.24e-06.
