We divide 708023 by 90
We want to divide 708023 by 90.

On to step 1:
If we divide 7 by 90, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 90

Advancing to step 2:
70 divided by 90 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Append the next digit (8) from the dividend to 70 and continue with: 708 / 90

Advancing to step 3:
90 can be fit into 708 7 times, resulting in a remainder of 78.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 630 from 708 and we're left with 78.
Append the next digit (0) from the dividend to 78 and continue with: 780 / 90

Step 4:
780 divided by 90 is 8 with a remainder of 60.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 60 after subtracting 720 from 780.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 90

Let's proceed to step 5:
602 divided by 90 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 786.0
The remainder is 62 after subtracting 540 from 602.
Bring next digit (3) of the dividend behind the 62 and repeat the process: 623 / 90

Step 6:
90 goes into 623 6 times with a remainder of 83.
Use 6 as the next digit of our solution. 
Result so far: 7866.0
Subtract 540 from 623 to get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 7:
90 can be fit into 830 9 times, resulting in a remainder of 20.
The number 9 becomes the next digit in our result. 
Result so far: 7866.9
If we take 810 away from 830, 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 8:
If we divide 200 by 90, we get 2 and a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 7866.92
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 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 7866.922
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.

The final result is 7866.922 with a remainder of 0.002.
