We're dividing 186419 by 12 
Our goal is to divide 186419 by 12.

Moving on to step 1:
The number 12 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 12

Step 2:
The number 12 fits into 18 1 times, leaving a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 12 from 18 leaves us with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 12

Let's proceed to step 3:
12 can be fit into 66 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 60 away from 66, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Moving on to step 4:
The number 12 fits into 64 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 155.0
If we take 60 away from 64, we end up with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Step 5:
12 can be fit into 41 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 1553.0
If we take 36 away from 41, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 12

Step 6:
59 divided by 12 is 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 15534.0
Deduct 48 from 59 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
12 goes into 110 9 times with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 15534.9
Subtracting 108 from 110 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 15534.91
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 15534.916
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 15534.9166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 15534.9166 with a balance of 8e-05.
