We divide 580090 by 78
Our goal is to divide 580090 by 78.

Going ahead to step 1:
If we divide 5 by 78, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 78

On to step 2:
78 goes into 58 0 times with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 78

Step 3:
When dividing 580 by 78, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 546 from 580 leaves us with 34.
Fetch the next digit (0) from the dividend, attach it to 34 and continue: 340 / 78

Moving on to step 4:
78 can be fit into 340 4 times, resulting in a remainder of 28.
The next digit of our result is 4. 
Result so far: 74.0
Subtract 312 from 340 to get 28.
Take the next digit (9) from the dividend and append it to 28, then repeat: 289 / 78

On to step 5:
78 goes into 289 3 times with a remainder of 55.
The number 3 becomes the next digit in our result. 
Result so far: 743.0
The remainder is 55 after subtracting 234 from 289.
Include the next digit (0) from the dividend after 55, then repeat: 550 / 78

Let's proceed to step 6:
If we divide 550 by 78, we get 7 and a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 7437.0
Subtracting 546 from 550 leaves us 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 7:
If we divide 40 by 78, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7437.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
400 divided by 78 is 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 7437.05
Subtracting 390 from 400 leaves us 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 9:
100 divided by 78 is 1 with a remainder of 22.
The next digit of our result is 1. 
Result so far: 7437.051
The remainder is 22 after subtracting 78 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
If we divide 220 by 78, we get 2 and a remainder of 64.
The number 2 becomes the next digit in our result. 
Result so far: 7437.0512
Subtracting 156 from 220 leaves us 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.

Moving on to step 11:
640 divided by 78 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 7437.05128
Deduct 624 from 640 and we're left 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.

Moving on to step 12:
If we divide 160 by 78, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 7437.051282
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
When dividing 40 by 78, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7437.051282
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 14:
78 goes into 400 5 times with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 7437.05128205
Deduct 390 from 400 and we're left 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.

The final result is 7437.05128205 with a remainder of 1e-08.
