We're dividing 869130 by 12 
We're looking to find how many times 12 goes into 869130.

Moving on to step 1:
When dividing 8 by 12, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 12

Moving on to step 2:
12 can be fit into 86 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 84 from 86 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 12

Going ahead to step 3:
12 can be fit into 29 2 times, resulting in a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
The remainder is 5 after subtracting 24 from 29.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 12

Advancing to step 4:
The number 12 fits into 51 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 724.0
The remainder is 3 after subtracting 48 from 51.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 12

Advancing to step 5:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 7242.0
Subtract 24 from 33 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 12

Let's proceed to step 6:
When dividing 90 by 12, we get 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 72427.0
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 72427.5
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 72427.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 72427.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 72427.5, with a leftover of 0.0.
