We divide 89720752 by 90
Let's see how many times 90 fits into 89720752.

Step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 90

Step 2:
When dividing 89 by 90, we get 0 with a remainder of 89.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Append the next digit (7) from the dividend to 89 and continue with: 897 / 90

Step 3:
When dividing 897 by 90, we get 9 with a remainder of 87.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 810 from 897, we get 87.
Append the next digit (2) from the dividend to 87 and continue with: 872 / 90

Advancing to step 4:
When dividing 872 by 90, we get 9 with a remainder of 62.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we subtract 810 from 872, we get 62.
Include the next digit (0) from the dividend after 62, then repeat: 620 / 90

Going ahead to step 5:
When dividing 620 by 90, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 996.0
If we take 540 away from 620, we end up with 80.
Fetch the next digit (7) from the dividend, attach it to 80 and continue: 807 / 90

Advancing to step 6:
807 divided by 90 is 8 with a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 9968.0
Subtracting 720 from 807 leaves us with 87.
Include the next digit (5) from the dividend after 87, then repeat: 875 / 90

Advancing to step 7:
When dividing 875 by 90, we get 9 with a remainder of 65.
Use 9 as the next digit of our solution. 
Result so far: 99689.0
Subtract 810 from 875 to get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 90

Advancing to step 8:
90 goes into 652 7 times with a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 996897.0
If we take 630 away from 652, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
90 can be fit into 220 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 996897.2
Subtracting 180 from 220 leaves us 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.

Advancing to step 10:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 996897.24
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
When dividing 400 by 90, we get 4 with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 996897.244
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 996897.244 with a balance of 0.004.
