72439726 divided by 12 
We're looking to find how many times 12 goes into 72439726.

Going ahead to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 12

Advancing to step 2:
12 can be fit into 72 6 times, resulting in a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 72 from 72 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 12

On to step 3:
If we divide 4 by 12, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 4 to get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Going ahead to step 4:
12 goes into 43 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 603.0
Subtract 36 from 43 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 12

Moving on to step 5:
12 can be fit into 79 6 times, resulting in a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 6036.0
If we take 72 away from 79, we end up with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 12

Advancing to step 6:
77 divided by 12 is 6 with a remainder of 5.
Write down 6 as next digit of the result. 
Result so far: 60366.0
The remainder is 5 after subtracting 72 from 77.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Moving on to step 7:
12 can be fit into 52 4 times, resulting in a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 603664.0
Subtracting 48 from 52 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 12

Let's proceed to step 8:
12 goes into 46 3 times with a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 6036643.0
The remainder is 10 after subtracting 36 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
12 can be fit into 100 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 6036643.8
If we take 96 away from 100, we end up 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.

Moving on to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 6036643.83
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.

Going ahead to step 11:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 6036643.833
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.

The final result is 6036643.833 with a remainder of 0.0004.
