We look at the division of 18307164 by 12 
We're looking to find how many times 12 goes into 18307164.

Moving on to step 1:
12 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 12

On to step 2:
12 can be fit into 18 1 times, resulting in a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 12 from 18.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 12

Going ahead to step 3:
When dividing 63 by 12, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 60 away from 63, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Advancing to step 4:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 152.0
If we take 24 away from 30, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 12

On to step 5:
When dividing 67 by 12, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 1525.0
Subtracting 60 from 67 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 12

Moving on to step 6:
If we divide 71 by 12, we get 5 and a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 15255.0
Deduct 60 from 71 and we're left with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 12

Moving on to step 7:
If we divide 116 by 12, we get 9 and a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 152559.0
Subtract 108 from 116 to get 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 12

Let's proceed to step 8:
84 divided by 12 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 1525597.0
If we take 84 away from 84, 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 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1525597.0
Deduct 0 from 0 and we're left 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.

Moving on to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1525597.0
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 1525597.0, with a leftover of 0.0.
