234421 divided by 12 
We want to figure out the number of times 234421 can be divided by 12.

Advancing to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Step 2:
12 can be fit into 23 1 times, resulting in a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 12 away from 23, we end up with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 12

Let's proceed to step 3:
If we divide 114 by 12, we get 9 and a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 108 from 114 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

On to step 4:
64 divided by 12 is 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 195.0
Deduct 60 from 64 and we're left with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 12

Step 5:
42 divided by 12 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 1953.0
Deduct 36 from 42 and we're left with 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

Moving on to step 6:
61 divided by 12 is 5 with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 19535.0
If we take 60 away from 61, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 19535.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
12 goes into 100 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 19535.08
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
When dividing 40 by 12, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 19535.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 19535.0833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 19535.0833 and a remainder of 4e-05.
