Let's divide 20973992 by 12
We want to figure out the number of times 20973992 can be divided by 12.

Let's proceed to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

On to step 2:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 12 away from 20, we end up with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 12

Step 3:
89 divided by 12 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 84 from 89 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 12

Step 4:
12 goes into 57 4 times with a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
The remainder is 9 after subtracting 48 from 57.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 12

Moving on to step 5:
93 divided by 12 is 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 1747.0
If we subtract 84 from 93, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 12

Moving on to step 6:
The number 12 fits into 99 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 17478.0
If we take 96 away from 99, we end up with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 12

Advancing to step 7:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 174783.0
If we subtract 36 from 39, we get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 12

Let's proceed to step 8:
When dividing 32 by 12, we get 2 with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1747832.0
Subtract 24 from 32 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 1747832.6
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 1747832.66
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 1747832.66, and the remainder is 0.008.
