We're dividing 49881264 by 129 
We want to figure out the number of times 49881264 can be divided by 129.

Step 1:
129 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 129

Let's proceed to step 2:
129 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Bring next digit (8) of the dividend behind the 49 and repeat the process: 498 / 129

Let's proceed to step 3:
When dividing 498 by 129, we get 3 with a remainder of 111.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 387 from 498 leaves us with 111.
Grab the next digit (8) from the dividend, add it to 111, then carry on: 1118 / 129

On to step 4:
The number 129 fits into 1118 8 times, leaving a remainder of 86.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Deduct 1032 from 1118 and we're left with 86.
Fetch the next digit (1) from the dividend, attach it to 86 and continue: 861 / 129

Let's proceed to step 5:
129 goes into 861 6 times with a remainder of 87.
Write down 6 as next digit of the result. 
Result so far: 386.0
If we take 774 away from 861, we end up with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 129

Moving on to step 6:
When dividing 872 by 129, we get 6 with a remainder of 98.
The number 6 becomes the next digit in our result. 
Result so far: 3866.0
If we subtract 774 from 872, we get 98.
Grab the next digit (6) from the dividend, add it to 98, then carry on: 986 / 129

Going ahead to step 7:
If we divide 986 by 129, we get 7 and a remainder of 83.
Write down 7 as next digit of the result. 
Result so far: 38667.0
The remainder is 83 after subtracting 903 from 986.
Take the next digit (4) from the dividend and append it to 83, then repeat: 834 / 129

Advancing to step 8:
The number 129 fits into 834 6 times, leaving a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 386676.0
Subtract 774 from 834 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 9:
129 can be fit into 600 4 times, resulting in a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 386676.4
Subtracting 516 from 600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 10:
When dividing 840 by 129, we get 6 with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 386676.46
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
If we divide 660 by 129, we get 5 and a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 386676.465
If we subtract 645 from 660, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
129 can be fit into 150 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 386676.4651
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
If we divide 210 by 129, we get 1 and a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 386676.46511
Deduct 129 from 210 and we're left with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final result is 386676.46511 with a remainder of 8.1e-05.
