Let's divide 763424 by 90
We want to divide 763424 by 90.

Moving on to step 1:
The number 90 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 90

Moving on to step 2:
90 can be fit into 76 0 times, resulting in a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 76 to get 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 90

Moving on to step 3:
763 divided by 90 is 8 with a remainder of 43.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 720 from 763 and we're left with 43.
Append the next digit (4) from the dividend to 43 and continue with: 434 / 90

Going ahead to step 4:
If we divide 434 by 90, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
The remainder is 74 after subtracting 360 from 434.
Include the next digit (2) from the dividend after 74, then repeat: 742 / 90

Step 5:
If we divide 742 by 90, we get 8 and a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 848.0
The remainder is 22 after subtracting 720 from 742.
Fetch the next digit (4) from the dividend, attach it to 22 and continue: 224 / 90

On to step 6:
224 divided by 90 is 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 8482.0
Subtract 180 from 224 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.

Going ahead to step 7:
440 divided by 90 is 4 with a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 8482.4
The remainder is 80 after subtracting 360 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 8482.48
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 8482.488
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 8482.488 and a remainder of 0.008.
