764905 ÷ 90 
We want to figure out the number of times 764905 can be divided by 90.

Moving on to step 1:
7 divided by 90 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 90

Going ahead to step 2:
90 goes into 76 0 times with a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Take the next digit (4) from the dividend and append it to 76, then repeat: 764 / 90

Step 3:
If we divide 764 by 90, we get 8 and a remainder of 44.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 720 from 764 and we're left with 44.
Include the next digit (9) from the dividend after 44, then repeat: 449 / 90

Step 4:
90 goes into 449 4 times with a remainder of 89.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 360 from 449 leaves us with 89.
Bring next digit (0) of the dividend behind the 89 and repeat the process: 890 / 90

Advancing to step 5:
90 can be fit into 890 9 times, resulting in a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 849.0
Deduct 810 from 890 and we're left with 80.
Fetch the next digit (5) from the dividend, attach it to 80 and continue: 805 / 90

Moving on to step 6:
805 divided by 90 is 8 with a remainder of 85.
Write down 8 as next digit of the result. 
Result so far: 8498.0
Subtract 720 from 805 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Step 7:
90 can be fit into 850 9 times, resulting in a remainder of 40.
The next digit of our result is 9. 
Result so far: 8498.9
If we subtract 810 from 850, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
400 divided by 90 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 8498.94
Deduct 360 from 400 and we're left 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.

Moving on to step 9:
If we divide 400 by 90, we get 4 and a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 8498.944
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 8498.944 and a remainder of 0.004.
