16443 divided by 12 
We want to divide 16443 by 12.

Advancing 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.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 12

Advancing to step 2:
If we divide 16 by 12, we get 1 and a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 12 from 16 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 12

Moving on to step 3:
When dividing 44 by 12, we get 3 with a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 8 after subtracting 36 from 44.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 12

Let's proceed to step 4:
The number 12 fits into 84 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 137.0
If we subtract 84 from 84, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Moving on to step 5:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 1370.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 6:
12 goes into 30 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1370.2
Subtract 24 from 30 to 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.

Moving on to step 7:
60 divided by 12 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1370.25
If we subtract 60 from 60, 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.

Advancing to step 8:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1370.25
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1370.25
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 1370.25 with a remaining 0.0.
