Let's divide 7760 by 90
We're looking to find how many times 90 goes into 7760.

Advancing to step 1:
7 divided by 90 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 90

Step 2:
90 goes into 77 0 times with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Bring next digit (6) of the dividend behind the 77 and repeat the process: 776 / 90

Step 3:
90 goes into 776 8 times with a remainder of 56.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 720 from 776, we get 56.
Append the next digit (0) from the dividend to 56 and continue with: 560 / 90

Moving on to step 4:
When dividing 560 by 90, we get 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 86.0
Deduct 540 from 560 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.

Going ahead to step 5:
90 can be fit into 200 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 86.2
Subtracting 180 from 200 leaves us 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.

Let's proceed to step 6:
90 goes into 200 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 86.22
Deduct 180 from 200 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.

Our division results in 86.22 with a remaining 0.02.
