Let's divide 717680 by 90
Let's see how many times 90 fits into 717680.

Moving on to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 90

Let's proceed to step 2:
If we divide 71 by 90, we get 0 and a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 71, we end up with 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 90

Going ahead to step 3:
If we divide 717 by 90, we get 7 and a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 630 from 717, we get 87.
Include the next digit (6) from the dividend after 87, then repeat: 876 / 90

Step 4:
If we divide 876 by 90, we get 9 and a remainder of 66.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Deduct 810 from 876 and we're left with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 90

Moving on to step 5:
90 goes into 668 7 times with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 797.0
If we take 630 away from 668, we end up with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 90

Going ahead to step 6:
The number 90 fits into 380 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 7974.0
If we take 360 away from 380, we end up 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.

Advancing to step 7:
If we divide 200 by 90, we get 2 and a remainder of 20.
The next digit of our result is 2. 
Result so far: 7974.2
If we take 180 away from 200, we end up 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.

On to step 8:
200 divided by 90 is 2 with a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 7974.22
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 7974.22 with a remainder of 0.02.
