89199999 divided by 99 
Let's see how many times 99 fits into 89199999.

Step 1:
99 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 99

Moving on to step 2:
If we divide 89 by 99, we get 0 and a remainder of 89.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Append the next digit (1) from the dividend to 89 and continue with: 891 / 99

Step 3:
99 can be fit into 891 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 891 from 891 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 99

On to step 4:
The number 99 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 99

Advancing to step 5:
99 divided by 99 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 901.0
Subtract 99 from 99 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 99

Let's proceed to step 6:
If we divide 9 by 99, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 9010.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 99

Advancing to step 7:
99 goes into 99 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 90101.0
If we take 99 away from 99, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 99

Let's proceed to step 8:
99 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 901010.0
Deduct 0 from 9 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
When dividing 90 by 99, we get 0 with a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 901010.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 10:
The number 99 fits into 900 9 times, leaving a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 901010.09
If we take 891 away from 900, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
99 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 901010.09
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 12:
The number 99 fits into 900 9 times, leaving a remainder of 9.
The next digit of our result is 9. 
Result so far: 901010.0909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 13:
99 goes into 90 0 times with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 901010.0909
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 14:
The number 99 fits into 900 9 times, leaving a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 901010.090909
Subtract 891 from 900 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 15:
If we divide 90 by 99, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 901010.090909
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 16:
99 can be fit into 900 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 901010.09090909
The remainder is 9 after subtracting 891 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 901010.09090909 and a remainder of 9e-09.
