9130309 divided by 999 
We want to divide 9130309 by 999.

On to step 1:
999 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 999

Advancing to step 2:
999 goes into 91 0 times with a remainder of 91.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Fetch the next digit (3) from the dividend, attach it to 91 and continue: 913 / 999

Moving on to step 3:
999 goes into 913 0 times with a remainder of 913.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 913 leaves us with 913.
Fetch the next digit (0) from the dividend, attach it to 913 and continue: 9130 / 999

On to step 4:
9130 divided by 999 is 9 with a remainder of 139.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 8991 away from 9130, we end up with 139.
Bring next digit (3) of the dividend behind the 139 and repeat the process: 1393 / 999

Moving on to step 5:
When dividing 1393 by 999, we get 1 with a remainder of 394.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtracting 999 from 1393 leaves us with 394.
Fetch the next digit (0) from the dividend, attach it to 394 and continue: 3940 / 999

Moving on to step 6:
999 goes into 3940 3 times with a remainder of 943.
Use 3 as the next digit of our solution. 
Result so far: 913.0
Subtracting 2997 from 3940 leaves us with 943.
Append the next digit (9) from the dividend to 943 and continue with: 9439 / 999

Step 7:
When dividing 9439 by 999, we get 9 with a remainder of 448.
Put 9 as the next digit of the answer. 
Result so far: 9139.0
The remainder is 448 after subtracting 8991 from 9439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Let's proceed to step 8:
4480 divided by 999 is 4 with a remainder of 484.
Write down 4 as next digit of the result. 
Result so far: 9139.4
Subtracting 3996 from 4480 leaves us with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Let's proceed to step 9:
If we divide 4840 by 999, we get 4 and a remainder of 844.
Write down 4 as next digit of the result. 
Result so far: 9139.44
If we subtract 3996 from 4840, we get 844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8440, and continue the process.

The quotient of the division is 9139.44, and the remainder is 0.844.
