Let's divide 22430 by 12
We want to divide 22430 by 12.

Advancing to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 12

Advancing to step 2:
When dividing 22 by 12, we get 1 with a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 12 from 22 and we're left with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 12

Let's proceed to step 3:
12 can be fit into 104 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 96 from 104 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 12

Advancing to step 4:
83 divided by 12 is 6 with a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 186.0
If we subtract 72 from 83, we get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 12

Step 5:
If we divide 110 by 12, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 1869.0
The remainder is 2 after subtracting 108 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 6:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 1869.1
Subtract 12 from 20 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.

Advancing to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 1869.16
If we subtract 72 from 80, we 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.

Moving on to step 8:
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: 1869.166
Deduct 72 from 80 and we're left 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.

The final outcome is 1869.166, with a leftover of 0.0008.
