We look at the division of 148920 by 12 
We're looking to find how many times 12 goes into 148920.

Let's proceed to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 12

Advancing to step 2:
12 can be fit into 14 1 times, resulting in a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 12 from 14 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Let's proceed to step 3:
28 divided by 12 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 24 from 28 and we're left with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

Going ahead to step 4:
12 goes into 49 4 times with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 48 from 49 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 12

Step 5:
12 goes into 12 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1241.0
Deduct 12 from 12 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 12

Let's proceed to step 6:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12410.0
Subtract 0 from 0 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.

On to step 7:
The number 12 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12410.0
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.

Step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12410.0
Subtract 0 from 0 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.

Our division results in 12410.0 with a remaining 0.0.
