20394839 ÷ 702 
Let's see how many times 702 fits into 20394839.

Step 1:
2 divided by 702 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 702

Moving on to step 2:
702 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 702

Advancing to step 3:
203 divided by 702 is 0 with a remainder of 203.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 203 after subtracting 0 from 203.
Bring next digit (9) of the dividend behind the 203 and repeat the process: 2039 / 702

On to step 4:
2039 divided by 702 is 2 with a remainder of 635.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 635 after subtracting 1404 from 2039.
Include the next digit (4) from the dividend after 635, then repeat: 6354 / 702

Moving on to step 5:
If we divide 6354 by 702, we get 9 and a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtract 6318 from 6354 to get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 702

On to step 6:
The number 702 fits into 368 0 times, leaving a remainder of 368.
Use 0 as the next digit of our solution. 
Result so far: 290.0
Deduct 0 from 368 and we're left with 368.
Fetch the next digit (3) from the dividend, attach it to 368 and continue: 3683 / 702

Moving on to step 7:
When dividing 3683 by 702, we get 5 with a remainder of 173.
The next digit of our result is 5. 
Result so far: 2905.0
The remainder is 173 after subtracting 3510 from 3683.
Include the next digit (9) from the dividend after 173, then repeat: 1739 / 702

Let's proceed to step 8:
When dividing 1739 by 702, we get 2 with a remainder of 335.
The next digit of our result is 2. 
Result so far: 29052.0
Deduct 1404 from 1739 and we're left with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
702 can be fit into 3350 4 times, resulting in a remainder of 542.
Use 4 as the next digit of our solution. 
Result so far: 29052.4
Subtracting 2808 from 3350 leaves us with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

On to step 10:
When dividing 5420 by 702, we get 7 with a remainder of 506.
Use 7 as the next digit of our solution. 
Result so far: 29052.47
If we take 4914 away from 5420, we end up with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Advancing to step 11:
The number 702 fits into 5060 7 times, leaving a remainder of 146.
The number 7 becomes the next digit in our result. 
Result so far: 29052.477
If we take 4914 away from 5060, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 29052.477, and the remainder is 0.0146.
