We're dividing 7309180 by 129 
We want to figure out the number of times 7309180 can be divided by 129.

Going ahead to step 1:
If we divide 7 by 129, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 129

Moving on to step 2:
73 divided by 129 is 0 with a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Fetch the next digit (0) from the dividend, attach it to 73 and continue: 730 / 129

Let's proceed to step 3:
730 divided by 129 is 5 with a remainder of 85.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 645 from 730 leaves us with 85.
Bring next digit (9) of the dividend behind the 85 and repeat the process: 859 / 129

Let's proceed to step 4:
When dividing 859 by 129, we get 6 with a remainder of 85.
The next digit of our result is 6. 
Result so far: 56.0
Subtracting 774 from 859 leaves us with 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 129

Let's proceed to step 5:
129 can be fit into 851 6 times, resulting in a remainder of 77.
Record the quotient 6 as the next digit in the result. 
Result so far: 566.0
If we take 774 away from 851, we end up with 77.
Bring next digit (8) of the dividend behind the 77 and repeat the process: 778 / 129

Moving on to step 6:
The number 129 fits into 778 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 5666.0
Subtract 774 from 778 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 129

On to step 7:
The number 129 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 56660.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
When dividing 400 by 129, we get 3 with a remainder of 13.
Write down 3 as next digit of the result. 
Result so far: 56660.3
Deduct 387 from 400 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
If we divide 130 by 129, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 56660.31
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
When dividing 10 by 129, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 56660.31
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 11:
129 goes into 100 0 times with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 56660.31
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 56660.31 with a remainder of 0.001.
