We look at the division of 76480 by 90 
Let's see how many times 90 fits into 76480.

Going ahead to step 1:
When dividing 7 by 90, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 90

Advancing to step 2:
When dividing 76 by 90, we get 0 with a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 76 leaves us with 76.
Fetch the next digit (4) from the dividend, attach it to 76 and continue: 764 / 90

Advancing to step 3:
When dividing 764 by 90, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 720 away from 764, we end up with 44.
Append the next digit (8) from the dividend to 44 and continue with: 448 / 90

Let's proceed to step 4:
90 goes into 448 4 times with a remainder of 88.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 88 after subtracting 360 from 448.
Bring next digit (0) of the dividend behind the 88 and repeat the process: 880 / 90

On to step 5:
880 divided by 90 is 9 with a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 849.0
If we take 810 away from 880, we end up with 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 6:
If we divide 700 by 90, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 849.7
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 7:
If we divide 700 by 90, we get 7 and a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 849.77
Subtract 630 from 700 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.

The final result is 849.77 with a remainder of 0.07.
