162921 ÷ 12 
Let's see how many times 12 fits into 162921.

On to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 12

Let's proceed to step 2:
12 can be fit into 16 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 16, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 12

On to step 3:
12 goes into 42 3 times with a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 6 after subtracting 36 from 42.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 12

Going ahead to step 4:
12 can be fit into 69 5 times, resulting in a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 135.0
Subtract 60 from 69 to get 9.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 12

Let's proceed to step 5:
92 divided by 12 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 1357.0
If we take 84 away from 92, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 12

Moving on to step 6:
12 can be fit into 81 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 13576.0
Subtract 72 from 81 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
12 can be fit into 90 7 times, resulting in a remainder of 6.
The next digit of our result is 7. 
Result so far: 13576.7
Subtracting 84 from 90 leaves us with 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 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 13576.75
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.

Let's proceed to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 13576.75
Subtracting 0 from 0 leaves us 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 10:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13576.75
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.

After the division, we end up with 13576.75 and a remainder of 0.0.
