We're dividing 7429419 by 12 
Our goal is to divide 7429419 by 12.

Step 1:
The number 12 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 12

Advancing to step 2:
When dividing 74 by 12, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 72 away from 74, we end up with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 12

Let's proceed to step 3:
When dividing 22 by 12, we get 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 12 from 22 to get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 12

Advancing to step 4:
When dividing 109 by 12, we get 9 with a remainder of 1.
The next digit of our result is 9. 
Result so far: 619.0
If we take 108 away from 109, we end up with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 12

On to step 5:
When dividing 14 by 12, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 6191.0
If we take 12 away from 14, we end up with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 12

Let's proceed to step 6:
12 goes into 21 1 times with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 61911.0
Subtract 12 from 21 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 12

Let's proceed to step 7:
99 divided by 12 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 619118.0
Subtracting 96 from 99 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 8:
When dividing 30 by 12, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 619118.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
When dividing 60 by 12, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 619118.25
If we subtract 60 from 60, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 619118.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 11:
0 divided by 12 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 619118.25
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 619118.25 with a balance of 0.0.
