We're dividing 20071107 by 129 
We're looking to find how many times 129 goes into 20071107.

Advancing to step 1:
When dividing 2 by 129, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 129

On to step 2:
129 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (0) from the dividend, attach it to 20 and continue: 200 / 129

Advancing to step 3:
200 divided by 129 is 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 1.0
If we take 129 away from 200, we end up with 71.
Grab the next digit (7) from the dividend, add it to 71, then carry on: 717 / 129

Moving on to step 4:
If we divide 717 by 129, we get 5 and a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
Subtracting 645 from 717 leaves us with 72.
Take the next digit (1) from the dividend and append it to 72, then repeat: 721 / 129

Advancing to step 5:
129 goes into 721 5 times with a remainder of 76.
Use 5 as the next digit of our solution. 
Result so far: 155.0
If we subtract 645 from 721, we get 76.
Append the next digit (1) from the dividend to 76 and continue with: 761 / 129

Advancing to step 6:
129 goes into 761 5 times with a remainder of 116.
Record the quotient 5 as the next digit in the result. 
Result so far: 1555.0
If we subtract 645 from 761, we get 116.
Take the next digit (0) from the dividend and append it to 116, then repeat: 1160 / 129

Let's proceed to step 7:
The number 129 fits into 1160 8 times, leaving a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 15558.0
Subtracting 1032 from 1160 leaves us with 128.
Append the next digit (7) from the dividend to 128 and continue with: 1287 / 129

Advancing to step 8:
129 can be fit into 1287 9 times, resulting in a remainder of 126.
Use 9 as the next digit of our solution. 
Result so far: 155589.0
The remainder is 126 after subtracting 1161 from 1287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Going ahead to step 9:
129 goes into 1260 9 times with a remainder of 99.
The number 9 becomes the next digit in our result. 
Result so far: 155589.9
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.

Let's proceed to step 10:
129 goes into 990 7 times with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 155589.97
If we subtract 903 from 990, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 11:
When dividing 870 by 129, we get 6 with a remainder of 96.
Record the quotient 6 as the next digit in the result. 
Result so far: 155589.976
If we take 774 away from 870, we end up 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.

Step 12:
129 goes into 960 7 times with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 155589.9767
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: 155589.97674
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.

Going ahead to step 14:
129 can be fit into 540 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 155589.976744
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.

The quotient of the division is 155589.976744, and the remainder is 2.4e-06.
