We're dividing 129190 by 18 
We want to figure out the number of times 129190 can be divided by 18.

Moving on to step 1:
1 divided by 18 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 18

Moving on to step 2:
When dividing 12 by 18, we get 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 18

Let's proceed to step 3:
The number 18 fits into 129 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 126 from 129 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 18

Step 4:
18 can be fit into 31 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 18 from 31 and we're left with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 18

Step 5:
18 can be fit into 139 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 717.0
The remainder is 13 after subtracting 126 from 139.
Fetch the next digit (0) from the dividend, attach it to 13 and continue: 130 / 18

Moving on to step 6:
If we divide 130 by 18, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 7177.0
If we take 126 away from 130, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
18 can be fit into 40 2 times, resulting in a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 7177.2
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 18 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 7177.22
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 7177.22 with a remainder of 0.004.
