73721 ÷ 12 
Let's see how many times 12 fits into 73721.

Advancing to step 1:
12 can be fit into 7 0 times, resulting in 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.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 12

Going ahead to step 2:
If we divide 73 by 12, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 72 from 73 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

Moving on to step 3:
If we divide 17 by 12, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 61.0
If we take 12 away from 17, we end up with 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 12

Advancing to step 4:
12 goes into 52 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 614.0
Subtract 48 from 52 to get 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 12

Going ahead to step 5:
The number 12 fits into 41 3 times, leaving a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 6143.0
Deduct 36 from 41 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 6:
50 divided by 12 is 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 6143.4
The remainder is 2 after subtracting 48 from 50.
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:
12 can be fit into 20 1 times, resulting in a remainder of 8.
The next digit of our result is 1. 
Result so far: 6143.41
Deduct 12 from 20 and we're left 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.

Advancing to step 8:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 6143.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 6143.4166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 6143.4166, with a leftover of 8e-05.
