Let's divide 49990555 by 129
We're looking to find how many times 129 goes into 49990555.

On to step 1:
If we divide 4 by 129, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 129

Let's proceed to step 2:
If we divide 49 by 129, we get 0 and a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 129

On to step 3:
499 divided by 129 is 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 387 from 499, we get 112.
Append the next digit (9) from the dividend to 112 and continue with: 1129 / 129

Step 4:
When dividing 1129 by 129, we get 8 with a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtracting 1032 from 1129 leaves us with 97.
Grab the next digit (0) from the dividend, add it to 97, then carry on: 970 / 129

On to step 5:
If we divide 970 by 129, we get 7 and a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 387.0
Subtracting 903 from 970 leaves us with 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 129

Step 6:
When dividing 675 by 129, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3875.0
If we subtract 645 from 675, we get 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 129

Let's proceed to step 7:
305 divided by 129 is 2 with a remainder of 47.
The next digit of our result is 2. 
Result so far: 38752.0
The remainder is 47 after subtracting 258 from 305.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 129

Advancing to step 8:
If we divide 475 by 129, we get 3 and a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 387523.0
Subtracting 387 from 475 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 9:
129 can be fit into 880 6 times, resulting in a remainder of 106.
Use 6 as the next digit of our solution. 
Result so far: 387523.6
Deduct 774 from 880 and we're left 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.

Let's proceed to step 10:
129 goes into 1060 8 times with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 387523.68
Subtracting 1032 from 1060 leaves us with 28.
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 11:
When dividing 280 by 129, we get 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 387523.682
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 12:
129 goes into 220 1 times with a remainder of 91.
Put 1 as the next digit of the answer. 
Result so far: 387523.6821
Deduct 129 from 220 and we're left 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.

On to step 13:
129 can be fit into 910 7 times, resulting in a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 387523.68217
Deduct 903 from 910 and we're left 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 14:
The number 129 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 387523.68217
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 15:
If we divide 700 by 129, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 387523.6821705
If we subtract 645 from 700, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 16:
If we divide 550 by 129, we get 4 and a remainder of 34.
The number 4 becomes the next digit in our result. 
Result so far: 387523.68217054
If we take 516 away from 550, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

In conclusion, the division gives 387523.68217054 with a balance of 3.4e-08.
