We're dividing 758390 by 80 
We want to divide 758390 by 80.

Going ahead to step 1:
When dividing 7 by 80, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 80

Moving on to step 2:
When dividing 75 by 80, we get 0 with a remainder of 75.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 75 leaves us with 75.
Grab the next digit (8) from the dividend, add it to 75, then carry on: 758 / 80

On to step 3:
If we divide 758 by 80, we get 9 and a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 720 from 758 to get 38.
Bring next digit (3) of the dividend behind the 38 and repeat the process: 383 / 80

On to step 4:
80 goes into 383 4 times with a remainder of 63.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 320 from 383 leaves us with 63.
Take the next digit (9) from the dividend and append it to 63, then repeat: 639 / 80

Step 5:
If we divide 639 by 80, we get 7 and a remainder of 79.
The number 7 becomes the next digit in our result. 
Result so far: 947.0
Subtracting 560 from 639 leaves us with 79.
Append the next digit (0) from the dividend to 79 and continue with: 790 / 80

Step 6:
If we divide 790 by 80, we get 9 and a remainder of 70.
Put 9 as the next digit of the answer. 
Result so far: 9479.0
Subtract 720 from 790 to 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.

Step 7:
700 divided by 80 is 8 with a remainder of 60.
Record the quotient 8 as the next digit in the result. 
Result so far: 9479.8
If we take 640 away from 700, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 8:
600 divided by 80 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 9479.87
If we take 560 away from 600, 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.

Let's proceed to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 9479.875
The remainder is 0 after subtracting 400 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
80 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9479.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 80 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 9479.875
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 9479.875 with a remainder of 0.0.
