Let's divide 339086 by 72
Let's see how many times 72 fits into 339086.

On to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 72

On to step 2:
The number 72 fits into 33 0 times, leaving a remainder of 33.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 33, we end up with 33.
Include the next digit (9) from the dividend after 33, then repeat: 339 / 72

Going ahead to step 3:
When dividing 339 by 72, we get 4 with a remainder of 51.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 288 from 339 to get 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 72

Moving on to step 4:
If we divide 510 by 72, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Subtract 504 from 510 to get 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 72

Let's proceed to step 5:
68 divided by 72 is 0 with a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 470.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 72

Step 6:
The number 72 fits into 686 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 4709.0
Subtracting 648 from 686 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
If we divide 380 by 72, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 4709.5
Subtract 360 from 380 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
The number 72 fits into 200 2 times, leaving a remainder of 56.
Record the quotient 2 as the next digit in the result. 
Result so far: 4709.52
If we subtract 144 from 200, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 9:
If we divide 560 by 72, we get 7 and a remainder of 56.
Put 7 as the next digit of the answer. 
Result so far: 4709.527
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 10:
When dividing 560 by 72, we get 7 with a remainder of 56.
Use 7 as the next digit of our solution. 
Result so far: 4709.5277
Subtracting 504 from 560 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 4709.5277, with a leftover of 0.00056.
