Let's divide 97728660 by 990
We want to figure out the number of times 97728660 can be divided by 990.

On to step 1:
The number 990 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 990

Step 2:
When dividing 97 by 990, we get 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 97 to get 97.
Fetch the next digit (7) from the dividend, attach it to 97 and continue: 977 / 990

Advancing to step 3:
977 divided by 990 is 0 with a remainder of 977.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 977, we end up with 977.
Append the next digit (2) from the dividend to 977 and continue with: 9772 / 990

Moving on to step 4:
When dividing 9772 by 990, we get 9 with a remainder of 862.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 8910 from 9772, we get 862.
Include the next digit (8) from the dividend after 862, then repeat: 8628 / 990

Let's proceed to step 5:
8628 divided by 990 is 8 with a remainder of 708.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
The remainder is 708 after subtracting 7920 from 8628.
Fetch the next digit (6) from the dividend, attach it to 708 and continue: 7086 / 990

Moving on to step 6:
If we divide 7086 by 990, we get 7 and a remainder of 156.
The next digit of our result is 7. 
Result so far: 987.0
Deduct 6930 from 7086 and we're left with 156.
Grab the next digit (6) from the dividend, add it to 156, then carry on: 1566 / 990

Let's proceed to step 7:
990 goes into 1566 1 times with a remainder of 576.
Put 1 as the next digit of the answer. 
Result so far: 9871.0
Subtract 990 from 1566 to get 576.
Take the next digit (0) from the dividend and append it to 576, then repeat: 5760 / 990

Moving on to step 8:
5760 divided by 990 is 5 with a remainder of 810.
Write down 5 as next digit of the result. 
Result so far: 98715.0
Subtract 4950 from 5760 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

On to step 9:
If we divide 8100 by 990, we get 8 and a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 98715.8
Deduct 7920 from 8100 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Moving on to step 10:
1800 divided by 990 is 1 with a remainder of 810.
The next digit of our result is 1. 
Result so far: 98715.81
Deduct 990 from 1800 and we're left with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 11:
If we divide 8100 by 990, we get 8 and a remainder of 180.
Use 8 as the next digit of our solution. 
Result so far: 98715.818
If we take 7920 away from 8100, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
990 can be fit into 1800 1 times, resulting in a remainder of 810.
The next digit of our result is 1. 
Result so far: 98715.8181
Subtracting 990 from 1800 leaves us with 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 13:
If we divide 8100 by 990, we get 8 and a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 98715.81818
The remainder is 180 after subtracting 7920 from 8100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 14:
When dividing 1800 by 990, we get 1 with a remainder of 810.
Record the quotient 1 as the next digit in the result. 
Result so far: 98715.818181
Subtract 990 from 1800 to get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

Step 15:
990 goes into 8100 8 times with a remainder of 180.
The number 8 becomes the next digit in our result. 
Result so far: 98715.8181818
If we take 7920 away from 8100, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 16:
If we divide 1800 by 990, we get 1 and a remainder of 810.
Record the quotient 1 as the next digit in the result. 
Result so far: 98715.81818181
If we subtract 990 from 1800, we get 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8100, and continue the process.

The final outcome is 98715.81818181, with a leftover of 8.1e-07.
