12259913 ÷ 6 
Our goal is to divide 12259913 by 6.

Let's proceed to step 1:
If we divide 1 by 6, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 6

Advancing to step 2:
If we divide 12 by 6, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 12 from 12 and we're left with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 6

Advancing to step 3:
When dividing 2 by 6, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 6

Moving on to step 4:
25 divided by 6 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 6

Going ahead to step 5:
6 goes into 19 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 2043.0
Deduct 18 from 19 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 6

Moving on to step 6:
6 can be fit into 19 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 20433.0
If we take 18 away from 19, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 6

Going ahead to step 7:
The number 6 fits into 11 1 times, leaving a remainder of 5.
The next digit of our result is 1. 
Result so far: 204331.0
If we take 6 away from 11, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 6

Step 8:
When dividing 53 by 6, we get 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 2043318.0
If we subtract 48 from 53, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
The number 6 fits into 50 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 2043318.8
If we subtract 48 from 50, we 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.

Advancing to step 10:
6 can be fit into 20 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 2043318.83
Deduct 18 from 20 and we're left with 2.
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 11:
6 can be fit into 20 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 2043318.833
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 2043318.833 with a balance of 0.0002.
