888989 divided by 90 
We want to figure out the number of times 888989 can be divided by 90.

Going ahead to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 90

Step 2:
If we divide 88 by 90, we get 0 and a remainder of 88.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 90

Going ahead to step 3:
90 goes into 888 9 times with a remainder of 78.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 810 from 888 to get 78.
Fetch the next digit (9) from the dividend, attach it to 78 and continue: 789 / 90

Let's proceed to step 4:
90 goes into 789 8 times with a remainder of 69.
Use 8 as the next digit of our solution. 
Result so far: 98.0
Subtract 720 from 789 to get 69.
Grab the next digit (8) from the dividend, add it to 69, then carry on: 698 / 90

Going ahead to step 5:
90 can be fit into 698 7 times, resulting in a remainder of 68.
Record the quotient 7 as the next digit in the result. 
Result so far: 987.0
If we take 630 away from 698, we end up with 68.
Append the next digit (9) from the dividend to 68 and continue with: 689 / 90

Let's proceed to step 6:
If we divide 689 by 90, we get 7 and a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 9877.0
Subtracting 630 from 689 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 7:
When dividing 590 by 90, we get 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 9877.6
The remainder is 50 after subtracting 540 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9877.65
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 90 is 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9877.655
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

After the division, we end up with 9877.655 and a remainder of 0.005.
