16055309 ÷ 129 
We want to figure out the number of times 16055309 can be divided by 129.

Advancing to step 1:
The number 129 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 129

On to step 2:
The number 129 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 129

Advancing to step 3:
129 can be fit into 160 1 times, resulting in a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 129 from 160 and we're left with 31.
Append the next digit (5) from the dividend to 31 and continue with: 315 / 129

Advancing to step 4:
The number 129 fits into 315 2 times, leaving a remainder of 57.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 258 away from 315, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 129

Let's proceed to step 5:
575 divided by 129 is 4 with a remainder of 59.
The number 4 becomes the next digit in our result. 
Result so far: 124.0
Subtracting 516 from 575 leaves us with 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 129

Advancing to step 6:
If we divide 593 by 129, we get 4 and a remainder of 77.
Put 4 as the next digit of the answer. 
Result so far: 1244.0
Deduct 516 from 593 and we're left with 77.
Include the next digit (0) from the dividend after 77, then repeat: 770 / 129

Step 7:
The number 129 fits into 770 5 times, leaving a remainder of 125.
Write down 5 as next digit of the result. 
Result so far: 12445.0
Subtracting 645 from 770 leaves us with 125.
Include the next digit (9) from the dividend after 125, then repeat: 1259 / 129

Moving on to step 8:
When dividing 1259 by 129, we get 9 with a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 124459.0
The remainder is 98 after subtracting 1161 from 1259.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 9:
980 divided by 129 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 124459.7
Deduct 903 from 980 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 10:
770 divided by 129 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 124459.75
Subtract 645 from 770 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 11:
129 goes into 1250 9 times with a remainder of 89.
Put 9 as the next digit of the answer. 
Result so far: 124459.759
The remainder is 89 after subtracting 1161 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 12:
If we divide 890 by 129, we get 6 and a remainder of 116.
The next digit of our result is 6. 
Result so far: 124459.7596
If we subtract 774 from 890, we get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 13:
129 can be fit into 1160 8 times, resulting in a remainder of 128.
The next digit of our result is 8. 
Result so far: 124459.75968
If we take 1032 away from 1160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 14:
129 can be fit into 1280 9 times, resulting in a remainder of 119.
Record the quotient 9 as the next digit in the result. 
Result so far: 124459.759689
If we subtract 1161 from 1280, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Let's proceed to step 15:
129 can be fit into 1190 9 times, resulting in a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 124459.7596899
If we take 1161 away from 1190, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 124459.7596899, with a leftover of 2.9e-07.
