We look at the division of 768190 by 90 
Let's see how many times 90 fits into 768190.

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
Subtracting 0 from 7 leaves us with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 90

Advancing to step 2:
90 goes into 76 0 times with a remainder of 76.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Bring next digit (8) of the dividend behind the 76 and repeat the process: 768 / 90

On to step 3:
If we divide 768 by 90, we get 8 and a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 720 from 768, we get 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 90

Step 4:
90 can be fit into 481 5 times, resulting in a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
Deduct 450 from 481 and we're left with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 90

Going ahead to step 5:
The number 90 fits into 319 3 times, leaving a remainder of 49.
The next digit of our result is 3. 
Result so far: 853.0
The remainder is 49 after subtracting 270 from 319.
Bring next digit (0) of the dividend behind the 49 and repeat the process: 490 / 90

Advancing to step 6:
490 divided by 90 is 5 with a remainder of 40.
Record the quotient 5 as the next digit in the result. 
Result so far: 8535.0
Deduct 450 from 490 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.

Going ahead to step 7:
If we divide 400 by 90, we get 4 and a remainder of 40.
The next digit of our result is 4. 
Result so far: 8535.4
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.

On to step 8:
If we divide 400 by 90, we get 4 and a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 8535.44
Subtract 360 from 400 to 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.

The final result is 8535.44 with a remainder of 0.04.
