743442 divided by 12 
Let's see how many times 12 fits into 743442.

Moving on to step 1:
7 divided by 12 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 12

On to step 2:
12 can be fit into 74 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 72 away from 74, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Going ahead to step 3:
The number 12 fits into 23 1 times, leaving a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
Subtract 12 from 23 to get 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Moving on to step 4:
If we divide 114 by 12, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 619.0
If we subtract 108 from 114, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

On to step 5:
If we divide 64 by 12, we get 5 and a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 6195.0
If we take 60 away from 64, we end up with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 12

On to step 6:
12 can be fit into 42 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 61953.0
Deduct 36 from 42 and we're left 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.

Let's proceed to step 7:
60 divided by 12 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 61953.5
If we take 60 away from 60, 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.

Moving on to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 61953.5
If we subtract 0 from 0, 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.

Moving on to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 61953.5
Subtracting 0 from 0 leaves us 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.

The quotient of the division is 61953.5, and the remainder is 0.0.
