141850 divided by 12 
Our goal is to divide 141850 by 12.

Going ahead to step 1:
If we divide 1 by 12, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 12

Step 2:
12 can be fit into 14 1 times, resulting in a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 12 from 14 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 12

Going ahead to step 3:
The number 12 fits into 21 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 12 from 21 and we're left with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 12

On to step 4:
98 divided by 12 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 118.0
Subtracting 96 from 98 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Step 5:
12 goes into 25 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 1182.0
If we subtract 24 from 25, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 12

On to step 6:
10 divided by 12 is 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 11820.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 11820.8
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 11820.83
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 11820.833
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.

Our division results in 11820.833 with a remaining 0.0004.
