We're dividing 129949 by 8 
We want to figure out the number of times 129949 can be divided by 8.

Advancing to step 1:
8 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 8

On to step 2:
When dividing 12 by 8, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 4 after subtracting 8 from 12.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 8

Advancing to step 3:
When dividing 49 by 8, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 48 from 49, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 8

Going ahead to step 4:
8 goes into 19 2 times with a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 162.0
If we take 16 away from 19, we end up with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 8

Let's proceed to step 5:
When dividing 34 by 8, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 1624.0
If we take 32 away from 34, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 8

Moving on to step 6:
The number 8 fits into 29 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 16243.0
Subtracting 24 from 29 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
8 can be fit into 50 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 16243.6
If we take 48 away from 50, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 8 fits into 20 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 16243.62
Deduct 16 from 20 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 16243.625
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
0 divided by 8 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16243.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
The number 8 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 16243.625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 16243.625, with a leftover of 0.0.
