We look at the division of 721881 by 6 
We're looking to find how many times 6 goes into 721881.

Let's proceed to step 1:
6 goes into 7 1 times with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 6 from 7, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 6

Moving on to step 2:
The number 6 fits into 12 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 0 after subtracting 12 from 12.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 6

Step 3:
The number 6 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 120.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 6

Step 4:
The number 6 fits into 18 3 times, leaving a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1203.0
Subtracting 18 from 18 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 6

Step 5:
If we divide 8 by 6, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 12031.0
Deduct 6 from 8 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 6

Advancing to step 6:
The number 6 fits into 21 3 times, leaving a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 120313.0
The remainder is 3 after subtracting 18 from 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 6, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 120313.5
The remainder is 0 after subtracting 30 from 30.
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 8:
The number 6 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120313.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
6 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 120313.5
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.

The final outcome is 120313.5, with a leftover of 0.0.
