580348 ÷ 78 
Our goal is to divide 580348 by 78.

Let's proceed to step 1:
When dividing 5 by 78, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 78

Let's proceed to step 2:
The number 78 fits into 58 0 times, leaving a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 78

Advancing to step 3:
78 goes into 580 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 34 after subtracting 546 from 580.
Include the next digit (3) from the dividend after 34, then repeat: 343 / 78

Advancing to step 4:
If we divide 343 by 78, we get 4 and a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 74.0
If we subtract 312 from 343, we get 31.
Fetch the next digit (4) from the dividend, attach it to 31 and continue: 314 / 78

Advancing to step 5:
78 goes into 314 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 744.0
Subtracting 312 from 314 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 78

Going ahead to step 6:
78 goes into 28 0 times with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 7440.0
Subtracting 0 from 28 leaves us 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.

Going ahead to step 7:
The number 78 fits into 280 3 times, leaving a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 7440.3
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.

Advancing to step 8:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 7440.35
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.

Going ahead to step 9:
78 goes into 700 8 times with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 7440.358
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.

Advancing to step 10:
78 can be fit into 760 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 7440.3589
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.

Advancing to step 11:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 7440.35897
The remainder is 34 after subtracting 546 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
340 divided by 78 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 7440.358974
Subtracting 312 from 340 leaves us 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.

Moving on to step 13:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 7440.3589743
If we subtract 234 from 280, 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 14:
The number 78 fits into 460 5 times, leaving a remainder of 70.
Put 5 as the next digit of the answer. 
Result so far: 7440.35897435
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.

The final outcome is 7440.35897435, with a leftover of 7e-08.
