We divide 580297 by 78
We're looking to find how many times 78 goes into 580297.

On to step 1:
78 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 78

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
Deduct 0 from 58 and we're left with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 78

On to step 3:
If we divide 580 by 78, we get 7 and a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtracting 546 from 580 leaves us with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 78

Going ahead to step 4:
78 goes into 342 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 74.0
Deduct 312 from 342 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 78

On to step 5:
78 goes into 309 3 times with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 743.0
Subtracting 234 from 309 leaves us with 75.
Bring next digit (7) of the dividend behind the 75 and repeat the process: 757 / 78

Advancing to step 6:
When dividing 757 by 78, we get 9 with a remainder of 55.
Put 9 as the next digit of the answer. 
Result so far: 7439.0
If we take 702 away from 757, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
78 goes into 550 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7439.7
If we take 546 away from 550, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 78 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7439.7
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
78 can be fit into 400 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 7439.705
If we take 390 away from 400, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
78 can be fit into 100 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 7439.7051
Subtracting 78 from 100 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 78 fits into 220 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 7439.70512
Deduct 156 from 220 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
78 goes into 640 8 times with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 7439.705128
Subtracting 624 from 640 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
78 can be fit into 160 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 7439.7051282
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
40 divided by 78 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7439.7051282
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 7439.7051282 with a remainder of 4e-08.
