142634 divided by 12 
Our goal is to divide 142634 by 12.

Going ahead to step 1:
1 divided by 12 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

Let's proceed to step 2:
The number 12 fits into 14 1 times, leaving a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 12 from 14 and we're left with 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 12

Let's proceed to step 3:
12 goes into 22 1 times with a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 12 from 22 and we're left with 10.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 12

Advancing to step 4:
If we divide 106 by 12, we get 8 and a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 118.0
The remainder is 10 after subtracting 96 from 106.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 12

Let's proceed to step 5:
If we divide 103 by 12, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1188.0
Subtracting 96 from 103 leaves us with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

Let's proceed to step 6:
12 can be fit into 74 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 11886.0
Subtracting 72 from 74 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.

Let's proceed to step 7:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 11886.1
If we take 12 away from 20, 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.

Going ahead to step 8:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11886.16
Deduct 72 from 80 and we're left 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.

Step 9:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 11886.166
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.

After the division, we end up with 11886.166 and a remainder of 0.0008.
