269029 ÷ 12 
We want to figure out the number of times 269029 can be divided by 12.

Step 1:
12 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 12

Step 2:
If we divide 26 by 12, we get 2 and a remainder of 2.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 2 after subtracting 24 from 26.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Going ahead to step 3:
If we divide 29 by 12, we get 2 and a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 24 away from 29, we end up with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 12

On to step 4:
12 can be fit into 50 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 224.0
Subtracting 48 from 50 leaves us with 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 12

On to step 5:
The number 12 fits into 22 1 times, leaving a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 2241.0
Deduct 12 from 22 and we're left with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 12

Moving on to step 6:
12 can be fit into 109 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 22419.0
Deduct 108 from 109 and we're left 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.

Advancing 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: 22419.0
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.

Step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 22419.08
If we subtract 96 from 100, we 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 22419.083
Subtracting 36 from 40 leaves us 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 10:
If we divide 40 by 12, we get 3 and a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 22419.0833
Deduct 36 from 40 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.

The final outcome is 22419.0833, with a leftover of 4e-05.
