580790 divided by 78 
We want to divide 580790 by 78.

Step 1:
5 divided by 78 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 78

Moving on to step 2:
78 can be fit into 58 0 times, resulting in a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (0) of the dividend behind the 58 and repeat the process: 580 / 78

On to step 3:
580 divided by 78 is 7 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.
Bring next digit (7) of the dividend behind the 34 and repeat the process: 347 / 78

Advancing to step 4:
78 can be fit into 347 4 times, resulting in a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 74.0
Subtract 312 from 347 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 78

On to step 5:
If we divide 359 by 78, we get 4 and a remainder of 47.
Write down 4 as next digit of the result. 
Result so far: 744.0
Subtract 312 from 359 to get 47.
Grab the next digit (0) from the dividend, add it to 47, then carry on: 470 / 78

Advancing to step 6:
470 divided by 78 is 6 with a remainder of 2.
The next digit of our result is 6. 
Result so far: 7446.0
If we take 468 away from 470, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 7446.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
200 divided by 78 is 2 with a remainder of 44.
The next digit of our result is 2. 
Result so far: 7446.02
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 9:
440 divided by 78 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 7446.025
If we take 390 away from 440, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 78, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 7446.0256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
320 divided by 78 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 7446.02564
The remainder is 8 after subtracting 312 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
78 goes into 80 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 7446.025641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
If we divide 20 by 78, we get 0 and a remainder of 20.
The next digit of our result is 0. 
Result so far: 7446.025641
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
78 can be fit into 200 2 times, resulting in a remainder of 44.
Write down 2 as next digit of the result. 
Result so far: 7446.02564102
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 7446.02564102 and a remainder of 4.4e-08.
