221279 ÷ 12 
We want to divide 221279 by 12.

Moving on to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

Step 2:
The number 12 fits into 22 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 12 from 22 to get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 12

Let's proceed to step 3:
101 divided by 12 is 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 96 from 101, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

On to step 4:
52 divided by 12 is 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 184.0
If we take 48 away from 52, we end up with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 12

Advancing to step 5:
12 goes into 47 3 times with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 1843.0
If we take 36 away from 47, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 12

Advancing to step 6:
The number 12 fits into 119 9 times, leaving a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 18439.0
If we subtract 108 from 119, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
If we divide 110 by 12, we get 9 and a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 18439.9
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 18439.91
The remainder is 8 after subtracting 12 from 20.
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 9:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 18439.916
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.

Let's proceed to step 10:
If we divide 80 by 12, we get 6 and a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 18439.9166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 18439.9166 with a remaining 8e-05.
