Let's divide 20737443 by 12
Our goal is to divide 20737443 by 12.

Step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Moving on to step 2:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 12 from 20 to get 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 12

Let's proceed to step 3:
87 divided by 12 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 84 from 87, we get 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 12

Let's proceed to step 4:
The number 12 fits into 33 2 times, leaving a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 172.0
The remainder is 9 after subtracting 24 from 33.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 12

Let's proceed to step 5:
12 goes into 97 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 1728.0
Subtracting 96 from 97 leaves us with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

On to step 6:
If we divide 14 by 12, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 17281.0
Deduct 12 from 14 and we're left with 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 12

Going ahead to step 7:
If we divide 24 by 12, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 172812.0
Subtracting 24 from 24 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Step 8:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 1728120.0
Deduct 0 from 3 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
30 divided by 12 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1728120.2
The remainder is 6 after subtracting 24 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1728120.25
Deduct 60 from 60 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.

Let's proceed to step 11:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1728120.25
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.

Moving on to step 12:
12 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1728120.25
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.

After the division, we end up with 1728120.25 and a remainder of 0.0.
