We divide 580239 by 78
Let's see how many times 78 fits into 580239.

Advancing to step 1:
78 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 78

Moving on to step 2:
The number 78 fits into 58 0 times, leaving a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Append the next digit (0) from the dividend to 58 and continue with: 580 / 78

Step 3:
78 goes into 580 7 times with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 34 after subtracting 546 from 580.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 78

Advancing to step 4:
78 can be fit into 342 4 times, resulting in a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtracting 312 from 342 leaves us with 30.
Take the next digit (3) from the dividend and append it to 30, then repeat: 303 / 78

Advancing to step 5:
If we divide 303 by 78, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Deduct 234 from 303 and we're left with 69.
Bring next digit (9) of the dividend behind the 69 and repeat the process: 699 / 78

Going ahead to step 6:
If we divide 699 by 78, we get 8 and a remainder of 75.
Use 8 as the next digit of our solution. 
Result so far: 7438.0
If we subtract 624 from 699, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 7:
When dividing 750 by 78, we get 9 with a remainder of 48.
The next digit of our result is 9. 
Result so far: 7438.9
If we subtract 702 from 750, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
78 goes into 480 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 7438.96
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
If we divide 120 by 78, we get 1 and a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 7438.961
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
If we divide 420 by 78, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7438.9615
Deduct 390 from 420 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 11:
78 goes into 300 3 times with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 7438.96153
Subtracting 234 from 300 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 12:
When dividing 660 by 78, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 7438.961538
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
360 divided by 78 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7438.9615384
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 14:
When dividing 480 by 78, we get 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 7438.96153846
If we take 468 away from 480, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 7438.96153846, and the remainder is 1.2e-08.
