We're dividing 149112 by 12 
Our goal is to divide 149112 by 12.

Moving on to step 1:
12 can be fit into 1 0 times, resulting in 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.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 12

On to step 2:
If we divide 14 by 12, we get 1 and a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 12 from 14 leaves us with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Let's proceed to step 3:
When dividing 29 by 12, we get 2 with a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 24 from 29 to get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 12

Let's proceed to step 4:
If we divide 51 by 12, we get 4 and a remainder of 3.
The next digit of our result is 4. 
Result so far: 124.0
Subtracting 48 from 51 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 12

Going ahead to step 5:
If we divide 31 by 12, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 1242.0
Subtracting 24 from 31 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 12

Going ahead to step 6:
The number 12 fits into 72 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 12426.0
Subtracting 72 from 72 leaves us 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.

Advancing to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12426.0
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.

Going ahead to step 8:
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: 12426.0
Subtracting 0 from 0 leaves us 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.

After the division, we end up with 12426.0 and a remainder of 0.0.
