Let's divide 309806 by 72
Our goal is to divide 309806 by 72.

Going ahead to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 72

Let's proceed to step 2:
The number 72 fits into 30 0 times, leaving a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 72

Going ahead to step 3:
72 goes into 309 4 times with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 288 away from 309, we end up with 21.
Take the next digit (8) from the dividend and append it to 21, then repeat: 218 / 72

Let's proceed to step 4:
72 can be fit into 218 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 216 from 218 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 72

On to step 5:
20 divided by 72 is 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 430.0
Deduct 0 from 20 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 72

Advancing to step 6:
72 can be fit into 206 2 times, resulting in a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 4302.0
Deduct 144 from 206 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 7:
72 can be fit into 620 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 4302.8
Subtracting 576 from 620 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 8:
The number 72 fits into 440 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 4302.86
The remainder is 8 after subtracting 432 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
If we divide 80 by 72, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 4302.861
Deduct 72 from 80 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.

Let's proceed to step 10:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4302.8611
Subtracting 72 from 80 leaves us 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.

In conclusion, the division gives 4302.8611 with a balance of 8e-05.
