10312944 ÷ 990 
We want to figure out the number of times 10312944 can be divided by 990.

Step 1:
990 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 990

Let's proceed to step 2:
The number 990 fits into 10 0 times, leaving a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 10 after subtracting 0 from 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 990

On to step 3:
990 can be fit into 103 0 times, resulting in a remainder of 103.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 103 leaves us with 103.
Grab the next digit (1) from the dividend, add it to 103, then carry on: 1031 / 990

Advancing to step 4:
990 can be fit into 1031 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 990 away from 1031, we end up with 41.
Bring next digit (2) of the dividend behind the 41 and repeat the process: 412 / 990

Step 5:
990 goes into 412 0 times with a remainder of 412.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 412 to get 412.
Fetch the next digit (9) from the dividend, attach it to 412 and continue: 4129 / 990

Let's proceed to step 6:
990 can be fit into 4129 4 times, resulting in a remainder of 169.
The number 4 becomes the next digit in our result. 
Result so far: 104.0
Deduct 3960 from 4129 and we're left with 169.
Append the next digit (4) from the dividend to 169 and continue with: 1694 / 990

On to step 7:
990 can be fit into 1694 1 times, resulting in a remainder of 704.
The next digit of our result is 1. 
Result so far: 1041.0
Deduct 990 from 1694 and we're left with 704.
Bring next digit (4) of the dividend behind the 704 and repeat the process: 7044 / 990

On to step 8:
If we divide 7044 by 990, we get 7 and a remainder of 114.
The number 7 becomes the next digit in our result. 
Result so far: 10417.0
Deduct 6930 from 7044 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 9:
If we divide 1140 by 990, we get 1 and a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 10417.1
If we subtract 990 from 1140, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 10:
The number 990 fits into 1500 1 times, leaving a remainder of 510.
Put 1 as the next digit of the answer. 
Result so far: 10417.11
If we take 990 away from 1500, we end up with 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5100, and continue the process.

After the division, we end up with 10417.11 and a remainder of 0.51.
