We look at the division of 20289360 by 709 
We're looking to find how many times 709 goes into 20289360.

Let's proceed to step 1:
If we divide 2 by 709, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 709

On to step 2:
If we divide 20 by 709, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 709

Advancing to step 3:
If we divide 202 by 709, we get 0 and a remainder of 202.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 202 and we're left with 202.
Append the next digit (8) from the dividend to 202 and continue with: 2028 / 709

Advancing to step 4:
2028 divided by 709 is 2 with a remainder of 610.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 610 after subtracting 1418 from 2028.
Bring next digit (9) of the dividend behind the 610 and repeat the process: 6109 / 709

Step 5:
6109 divided by 709 is 8 with a remainder of 437.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 5672 from 6109 leaves us with 437.
Bring next digit (3) of the dividend behind the 437 and repeat the process: 4373 / 709

Step 6:
The number 709 fits into 4373 6 times, leaving a remainder of 119.
Use 6 as the next digit of our solution. 
Result so far: 286.0
The remainder is 119 after subtracting 4254 from 4373.
Fetch the next digit (6) from the dividend, attach it to 119 and continue: 1196 / 709

Let's proceed to step 7:
The number 709 fits into 1196 1 times, leaving a remainder of 487.
The next digit of our result is 1. 
Result so far: 2861.0
If we subtract 709 from 1196, we get 487.
Append the next digit (0) from the dividend to 487 and continue with: 4870 / 709

Advancing to step 8:
709 can be fit into 4870 6 times, resulting in a remainder of 616.
Record the quotient 6 as the next digit in the result. 
Result so far: 28616.0
If we subtract 4254 from 4870, we get 616.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6160, and continue the process.

Advancing to step 9:
The number 709 fits into 6160 8 times, leaving a remainder of 488.
The next digit of our result is 8. 
Result so far: 28616.8
If we take 5672 away from 6160, we end up with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

On to step 10:
709 goes into 4880 6 times with a remainder of 626.
The number 6 becomes the next digit in our result. 
Result so far: 28616.86
The remainder is 626 after subtracting 4254 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6260, and continue the process.

On to step 11:
709 can be fit into 6260 8 times, resulting in a remainder of 588.
Use 8 as the next digit of our solution. 
Result so far: 28616.868
If we take 5672 away from 6260, we end up with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Let's proceed to step 12:
709 goes into 5880 8 times with a remainder of 208.
Use 8 as the next digit of our solution. 
Result so far: 28616.8688
Deduct 5672 from 5880 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

After the division, we end up with 28616.8688 and a remainder of 0.00208.
