We're dividing 90485889 by 99 
Our goal is to divide 90485889 by 99.

Moving on to step 1:
99 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 99

Going ahead to step 2:
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: 0.0
The remainder is 90 after subtracting 0 from 90.
Include the next digit (4) from the dividend after 90, then repeat: 904 / 99

On to step 3:
If we divide 904 by 99, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 891 away from 904, we end up with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 99

Moving on to step 4:
If we divide 138 by 99, we get 1 and a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 91.0
If we subtract 99 from 138, we get 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 99

Let's proceed to step 5:
99 goes into 395 3 times with a remainder of 98.
Use 3 as the next digit of our solution. 
Result so far: 913.0
Deduct 297 from 395 and we're left with 98.
Append the next digit (8) from the dividend to 98 and continue with: 988 / 99

On to step 6:
The number 99 fits into 988 9 times, leaving a remainder of 97.
Write down 9 as next digit of the result. 
Result so far: 9139.0
Subtract 891 from 988 to get 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 99

Going ahead to step 7:
If we divide 978 by 99, we get 9 and a remainder of 87.
Write down 9 as next digit of the result. 
Result so far: 91399.0
Subtract 891 from 978 to get 87.
Bring next digit (9) of the dividend behind the 87 and repeat the process: 879 / 99

Let's proceed to step 8:
99 can be fit into 879 8 times, resulting in a remainder of 87.
Record the quotient 8 as the next digit in the result. 
Result so far: 913998.0
Subtract 792 from 879 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Let's proceed to step 9:
99 goes into 870 8 times with a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 913998.8
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 10:
The number 99 fits into 780 7 times, leaving a remainder of 87.
The next digit of our result is 7. 
Result so far: 913998.87
If we subtract 693 from 780, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 11:
When dividing 870 by 99, we get 8 with a remainder of 78.
Write down 8 as next digit of the result. 
Result so far: 913998.878
The remainder is 78 after subtracting 792 from 870.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 12:
780 divided by 99 is 7 with a remainder of 87.
The next digit of our result is 7. 
Result so far: 913998.8787
If we take 693 away from 780, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

On to step 13:
870 divided by 99 is 8 with a remainder of 78.
The next digit of our result is 8. 
Result so far: 913998.87878
Subtracting 792 from 870 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 14:
780 divided by 99 is 7 with a remainder of 87.
Put 7 as the next digit of the answer. 
Result so far: 913998.878787
Subtract 693 from 780 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 15:
When dividing 870 by 99, we get 8 with a remainder of 78.
Use 8 as the next digit of our solution. 
Result so far: 913998.8787878
Deduct 792 from 870 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 16:
780 divided by 99 is 7 with a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 913998.87878787
Subtracting 693 from 780 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Our division results in 913998.87878787 with a remaining 8.7e-08.
