We look at the division of 30707901 by 129 
We're looking to find how many times 129 goes into 30707901.

Step 1:
129 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 129

Step 2:
30 divided by 129 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 129

Step 3:
When dividing 307 by 129, we get 2 with a remainder of 49.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 49 after subtracting 258 from 307.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 129

Moving on to step 4:
When dividing 490 by 129, we get 3 with a remainder of 103.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 387 from 490 leaves us with 103.
Fetch the next digit (7) from the dividend, attach it to 103 and continue: 1037 / 129

Step 5:
If we divide 1037 by 129, we get 8 and a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
If we subtract 1032 from 1037, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 129

Moving on to step 6:
59 divided by 129 is 0 with a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 2380.0
Subtract 0 from 59 to get 59.
Bring next digit (0) of the dividend behind the 59 and repeat the process: 590 / 129

On to step 7:
129 can be fit into 590 4 times, resulting in a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 23804.0
If we take 516 away from 590, we end up with 74.
Include the next digit (1) from the dividend after 74, then repeat: 741 / 129

Advancing to step 8:
If we divide 741 by 129, we get 5 and a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 238045.0
Subtracting 645 from 741 leaves us 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 9:
129 can be fit into 960 7 times, resulting in a remainder of 57.
Write down 7 as next digit of the result. 
Result so far: 238045.7
Subtracting 903 from 960 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 10:
When dividing 570 by 129, we get 4 with a remainder of 54.
The next digit of our result is 4. 
Result so far: 238045.74
Deduct 516 from 570 and we're left with 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 11:
129 goes into 540 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 238045.744
Deduct 516 from 540 and we're left 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.

After the division, we end up with 238045.744 and a remainder of 0.0024.
