721994 ÷ 12 
We want to divide 721994 by 12.

On to step 1:
If we divide 7 by 12, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 12

On to step 2:
The number 12 fits into 72 6 times, leaving a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 72 from 72 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 12

Step 3:
When dividing 1 by 12, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtract 0 from 1 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 12

Moving on to step 4:
The number 12 fits into 19 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 601.0
Subtracting 12 from 19 leaves us with 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 12

Going ahead to step 5:
12 can be fit into 79 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 6016.0
Deduct 72 from 79 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 12

Going ahead to step 6:
If we divide 74 by 12, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 60166.0
If we subtract 72 from 74, 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.

Let's proceed to step 7:
20 divided by 12 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 60166.1
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 60166.16
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 60166.166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 60166.166 with a remaining 0.0008.
