We look at the division of 15536370 by 129 
Our goal is to divide 15536370 by 129.

Step 1:
129 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
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 129

Moving on to step 2:
129 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 129

Let's proceed to step 3:
When dividing 155 by 129, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 129 from 155 leaves us with 26.
Grab the next digit (3) from the dividend, add it to 26, then carry on: 263 / 129

Step 4:
If we divide 263 by 129, we get 2 and a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 258 from 263, we get 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 129

Going ahead to step 5:
When dividing 56 by 129, we get 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtract 0 from 56 to get 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 129

Moving on to step 6:
If we divide 563 by 129, we get 4 and a remainder of 47.
The next digit of our result is 4. 
Result so far: 1204.0
If we subtract 516 from 563, we get 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 129

Advancing to step 7:
477 divided by 129 is 3 with a remainder of 90.
Use 3 as the next digit of our solution. 
Result so far: 12043.0
Subtract 387 from 477 to get 90.
Grab the next digit (0) from the dividend, add it to 90, then carry on: 900 / 129

Moving on to step 8:
The number 129 fits into 900 6 times, leaving a remainder of 126.
Write down 6 as next digit of the result. 
Result so far: 120436.0
The remainder is 126 after subtracting 774 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Advancing to step 9:
129 goes into 1260 9 times with a remainder of 99.
The next digit of our result is 9. 
Result so far: 120436.9
Subtracting 1161 from 1260 leaves us with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

Going ahead to step 10:
990 divided by 129 is 7 with a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 120436.97
The remainder is 87 after subtracting 903 from 990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 11:
129 can be fit into 870 6 times, resulting in a remainder of 96.
The next digit of our result is 6. 
Result so far: 120436.976
Deduct 774 from 870 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 12:
If we divide 960 by 129, we get 7 and a remainder of 57.
Put 7 as the next digit of the answer. 
Result so far: 120436.9767
Subtract 903 from 960 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
The number 129 fits into 570 4 times, leaving a remainder of 54.
The next digit of our result is 4. 
Result so far: 120436.97674
Subtract 516 from 570 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 14:
129 can be fit into 540 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 120436.976744
If we take 516 away from 540, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 120436.976744 with a balance of 2.4e-06.
