We divide 186573 by 12
We're looking to find how many times 12 goes into 186573.

Going ahead to step 1:
12 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 12

Moving on to step 2:
If we divide 18 by 12, we get 1 and a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 12 from 18 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 12

Going ahead to step 3:
If we divide 66 by 12, we get 5 and a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 60 from 66 to get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 12

Advancing to step 4:
12 can be fit into 65 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
If we take 60 away from 65, we end up with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 12

On to step 5:
When dividing 57 by 12, we get 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 1554.0
Subtract 48 from 57 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 12

On to step 6:
When dividing 93 by 12, we get 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 15547.0
Subtract 84 from 93 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
90 divided by 12 is 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 15547.7
Subtracting 84 from 90 leaves us with 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 8:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 15547.75
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 15547.75
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.

Let's proceed to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 15547.75
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.

Our division results in 15547.75 with a remaining 0.0.
