We're dividing 584599 by 78 
Let's see how many times 78 fits into 584599.

Step 1:
The number 78 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 78

Moving on to step 2:
If we divide 58 by 78, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Append the next digit (4) from the dividend to 58 and continue with: 584 / 78

Step 3:
78 can be fit into 584 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 7.0
If we take 546 away from 584, we end up with 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 78

Moving on to step 4:
385 divided by 78 is 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 312 from 385 and we're left with 73.
Grab the next digit (9) from the dividend, add it to 73, then carry on: 739 / 78

Going ahead to step 5:
78 goes into 739 9 times with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 749.0
The remainder is 37 after subtracting 702 from 739.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 78

Moving on to step 6:
78 goes into 379 4 times with a remainder of 67.
Record the quotient 4 as the next digit in the result. 
Result so far: 7494.0
The remainder is 67 after subtracting 312 from 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
78 goes into 670 8 times with a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 7494.8
If we subtract 624 from 670, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
When dividing 460 by 78, we get 5 with a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 7494.85
If we subtract 390 from 460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
When dividing 700 by 78, we get 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 7494.858
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 10:
The number 78 fits into 760 9 times, leaving a remainder of 58.
The number 9 becomes the next digit in our result. 
Result so far: 7494.8589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 11:
580 divided by 78 is 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7494.85897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
340 divided by 78 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 7494.858974
Deduct 312 from 340 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
78 can be fit into 280 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 7494.8589743
Deduct 234 from 280 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 14:
When dividing 460 by 78, we get 5 with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 7494.85897435
If we take 390 away from 460, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 7494.85897435, with a leftover of 7e-08.
