We're dividing 146502 by 12 
Our goal is to divide 146502 by 12.

Advancing 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 (4) from the dividend and append it to 1, then repeat: 14 / 12

Going ahead to step 2:
The number 12 fits into 14 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 12 away from 14, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

Going ahead to step 3:
12 can be fit into 26 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 12.0
If we take 24 away from 26, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Step 4:
12 goes into 25 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 24 from 25, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 12

Moving on to step 5:
If we divide 10 by 12, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1220.0
Subtract 0 from 10 to get 10.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 12

Advancing to step 6:
12 goes into 102 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 12208.0
If we subtract 96 from 102, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 12 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12208.5
The remainder is 0 after subtracting 60 from 60.
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:
12 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 12208.5
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.

Step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12208.5
If we subtract 0 from 0, we 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 12208.5 with a remaining 0.0.
