We're dividing 72289 by 6 
Let's see how many times 6 fits into 72289.

Step 1:
6 can be fit into 7 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 6

Going ahead to step 2:
6 can be fit into 12 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 12 from 12, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 6

Moving on to step 3:
2 divided by 6 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 120.0
If we take 0 away from 2, we end up with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 6

Let's proceed to step 4:
The number 6 fits into 28 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 1204.0
Subtracting 24 from 28 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 6

On to step 5:
The number 6 fits into 49 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 12048.0
The remainder is 1 after subtracting 48 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 6:
When dividing 10 by 6, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 12048.1
Subtract 6 from 10 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 7:
6 can be fit into 40 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 12048.16
Deduct 36 from 40 and we're left 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.

On to step 8:
6 can be fit into 40 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 12048.166
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 12048.166 with a remainder of 0.0004.
