We divide 78302309 by 34
We want to figure out the number of times 78302309 can be divided by 34.

On to step 1:
When dividing 7 by 34, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 34

On to step 2:
34 goes into 78 2 times with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 10 after subtracting 68 from 78.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 34

Let's proceed to step 3:
If we divide 103 by 34, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 102 from 103 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 34

On to step 4:
34 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 230.0
The remainder is 10 after subtracting 0 from 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 34

On to step 5:
The number 34 fits into 102 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 2303.0
Subtracting 102 from 102 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 34

Advancing to step 6:
34 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 23030.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 34

Let's proceed to step 7:
34 goes into 30 0 times with a remainder of 30.
The next digit of our result is 0. 
Result so far: 230300.0
If we subtract 0 from 30, we get 30.
Append the next digit (9) from the dividend to 30 and continue with: 309 / 34

On to step 8:
34 goes into 309 9 times with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 2303009.0
If we subtract 306 from 309, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
30 divided by 34 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 2303009.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
The number 34 fits into 300 8 times, leaving a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 2303009.08
If we subtract 272 from 300, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 11:
If we divide 280 by 34, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 2303009.088
If we subtract 272 from 280, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 2303009.088 with a remainder of 0.0008.
