We're dividing 6449902 by 129 
We're looking to find how many times 129 goes into 6449902.

Advancing to step 1:
129 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 129

Going ahead to step 2:
When dividing 64 by 129, we get 0 with a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 129

Advancing to step 3:
129 can be fit into 644 4 times, resulting in a remainder of 128.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 516 from 644 leaves us with 128.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 129

Moving on to step 4:
1289 divided by 129 is 9 with a remainder of 128.
Put 9 as the next digit of the answer. 
Result so far: 49.0
The remainder is 128 after subtracting 1161 from 1289.
Take the next digit (9) from the dividend and append it to 128, then repeat: 1289 / 129

Going ahead to step 5:
1289 divided by 129 is 9 with a remainder of 128.
Use 9 as the next digit of our solution. 
Result so far: 499.0
If we take 1161 away from 1289, we end up with 128.
Include the next digit (0) from the dividend after 128, then repeat: 1280 / 129

Advancing to step 6:
If we divide 1280 by 129, we get 9 and a remainder of 119.
Write down 9 as next digit of the result. 
Result so far: 4999.0
If we subtract 1161 from 1280, we get 119.
Grab the next digit (2) from the dividend, add it to 119, then carry on: 1192 / 129

On to step 7:
1192 divided by 129 is 9 with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 49999.0
The remainder is 31 after subtracting 1161 from 1192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 8:
The number 129 fits into 310 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 49999.2
If we subtract 258 from 310, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
129 goes into 520 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 49999.24
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
If we divide 40 by 129, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 49999.24
If we take 0 away from 40, we end up 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.

Moving on to step 11:
129 can be fit into 400 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 49999.2403
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
The number 129 fits into 130 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 49999.24031
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
When dividing 10 by 129, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 49999.24031
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
When dividing 100 by 129, we get 0 with a remainder of 100.
The next digit of our result is 0. 
Result so far: 49999.24031
If we subtract 0 from 100, we get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final outcome is 49999.24031, with a leftover of 1e-06.
