We look at the division of 726459 by 12 
Let's see how many times 12 fits into 726459.

Let's proceed to step 1:
12 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

Going ahead to step 2:
If we divide 72 by 12, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 72 away from 72, we end up with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 12

Going ahead to step 3:
6 divided by 12 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 60.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 12

On to step 4:
12 goes into 64 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 605.0
If we subtract 60 from 64, we get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 12

Step 5:
45 divided by 12 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 6053.0
If we take 36 away from 45, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 12

Advancing to step 6:
When dividing 99 by 12, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 60538.0
Subtract 96 from 99 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 12, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 60538.2
Deduct 24 from 30 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.

Advancing to step 8:
If we divide 60 by 12, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 60538.25
Deduct 60 from 60 and we're left 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 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 60538.25
Deduct 0 from 0 and we're left 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.

Advancing to step 10:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 60538.25
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.

The final outcome is 60538.25, with a leftover of 0.0.
