The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 129

Going ahead to step 2:
When dividing 79 by 129, we get 0 with a remainder of 79.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Include the next digit (3) from the dividend after 79, then repeat: 793 / 129

On to step 3:
The number 129 fits into 793 6 times, leaving a remainder of 19.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 774 from 793 and we're left with 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 129

Going ahead to step 4:
When dividing 191 by 129, we get 1 with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Subtracting 129 from 191 leaves us with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 129

Let's proceed to step 5:
129 can be fit into 628 4 times, resulting in a remainder of 112.
The next digit of our result is 4. 
Result so far: 614.0
Subtract 516 from 628 to get 112.
Take the next digit (0) from the dividend and append it to 112, then repeat: 1120 / 129

Advancing to step 6:
When dividing 1120 by 129, we get 8 with a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 6148.0
If we subtract 1032 from 1120, we get 88.
Include the next digit (8) from the dividend after 88, then repeat: 888 / 129

Advancing to step 7:
If we divide 888 by 129, we get 6 and a remainder of 114.
Put 6 as the next digit of the answer. 
Result so far: 61486.0
Subtract 774 from 888 to get 114.
Include the next digit (7) from the dividend after 114, then repeat: 1147 / 129

Step 8:
If we divide 1147 by 129, we get 8 and a remainder of 115.
Record the quotient 8 as the next digit in the result. 
Result so far: 614868.0
Subtract 1032 from 1147 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
129 goes into 1150 8 times with a remainder of 118.
Write down 8 as next digit of the result. 
Result so far: 614868.8
The remainder is 118 after subtracting 1032 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Advancing to step 10:
When dividing 1180 by 129, we get 9 with a remainder of 19.
The number 9 becomes the next digit in our result. 
Result so far: 614868.89
The remainder is 19 after subtracting 1161 from 1180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 11:
The number 129 fits into 190 1 times, leaving a remainder of 61.
The number 1 becomes the next digit in our result. 
Result so far: 614868.891
Deduct 129 from 190 and we're left with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 12:
When dividing 610 by 129, we get 4 with a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 614868.8914
If we take 516 away from 610, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 13:
129 can be fit into 940 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 614868.89147
If we subtract 903 from 940, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
370 divided by 129 is 2 with a remainder of 112.
The next digit of our result is 2. 
Result so far: 614868.891472
Subtract 258 from 370 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Step 15:
1120 divided by 129 is 8 with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 614868.8914728
If we take 1032 away from 1120, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
129 goes into 880 6 times with a remainder of 106.
The next digit of our result is 6. 
Result so far: 614868.89147286
Subtract 774 from 880 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Our division results in 614868.89147286 with a remaining 1.06e-07.
