Let's divide 78309200 by 579
We're looking to find how many times 579 goes into 78309200.

Step 1:
The number 579 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 579

Going ahead to step 2:
When dividing 78 by 579, we get 0 with a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 579

On to step 3:
If we divide 783 by 579, we get 1 and a remainder of 204.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 579 from 783 to get 204.
Fetch the next digit (0) from the dividend, attach it to 204 and continue: 2040 / 579

Let's proceed to step 4:
579 goes into 2040 3 times with a remainder of 303.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 1737 from 2040, we get 303.
Grab the next digit (9) from the dividend, add it to 303, then carry on: 3039 / 579

Step 5:
The number 579 fits into 3039 5 times, leaving a remainder of 144.
The next digit of our result is 5. 
Result so far: 135.0
If we take 2895 away from 3039, we end up with 144.
Include the next digit (2) from the dividend after 144, then repeat: 1442 / 579

Going ahead to step 6:
When dividing 1442 by 579, we get 2 with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 1352.0
Subtracting 1158 from 1442 leaves us with 284.
Include the next digit (0) from the dividend after 284, then repeat: 2840 / 579

Moving on to step 7:
579 goes into 2840 4 times with a remainder of 524.
The number 4 becomes the next digit in our result. 
Result so far: 13524.0
Deduct 2316 from 2840 and we're left with 524.
Append the next digit (0) from the dividend to 524 and continue with: 5240 / 579

Step 8:
579 goes into 5240 9 times with a remainder of 29.
The next digit of our result is 9. 
Result so far: 135249.0
Subtract 5211 from 5240 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 579 fits into 290 0 times, leaving a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 135249.0
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Moving on to step 10:
579 can be fit into 2900 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 135249.05
Subtract 2895 from 2900 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 579, we get 0 with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 135249.05
Subtract 0 from 50 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
If we divide 500 by 579, we get 0 and a remainder of 500.
Record the quotient 0 as the next digit in the result. 
Result so far: 135249.05
If we subtract 0 from 500, we get 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

The final outcome is 135249.05, with a leftover of 0.005.
