We divide 5122099 by 990
We want to divide 5122099 by 990.

Let's proceed to step 1:
The number 990 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 990

Going ahead to step 2:
990 can be fit into 51 0 times, resulting in a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Grab the next digit (2) from the dividend, add it to 51, then carry on: 512 / 990

Let's proceed to step 3:
990 can be fit into 512 0 times, resulting in a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 512 after subtracting 0 from 512.
Bring next digit (2) of the dividend behind the 512 and repeat the process: 5122 / 990

Let's proceed to step 4:
When dividing 5122 by 990, we get 5 with a remainder of 172.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 4950 from 5122 leaves us with 172.
Take the next digit (0) from the dividend and append it to 172, then repeat: 1720 / 990

Step 5:
990 can be fit into 1720 1 times, resulting in a remainder of 730.
The next digit of our result is 1. 
Result so far: 51.0
If we take 990 away from 1720, we end up with 730.
Append the next digit (9) from the dividend to 730 and continue with: 7309 / 990

Going ahead to step 6:
7309 divided by 990 is 7 with a remainder of 379.
Use 7 as the next digit of our solution. 
Result so far: 517.0
The remainder is 379 after subtracting 6930 from 7309.
Fetch the next digit (9) from the dividend, attach it to 379 and continue: 3799 / 990

Step 7:
3799 divided by 990 is 3 with a remainder of 829.
Write down 3 as next digit of the result. 
Result so far: 5173.0
Subtracting 2970 from 3799 leaves us with 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Advancing to step 8:
990 can be fit into 8290 8 times, resulting in a remainder of 370.
Put 8 as the next digit of the answer. 
Result so far: 5173.8
If we take 7920 away from 8290, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 9:
If we divide 3700 by 990, we get 3 and a remainder of 730.
Put 3 as the next digit of the answer. 
Result so far: 5173.83
Subtract 2970 from 3700 to get 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Going ahead to step 10:
If we divide 7300 by 990, we get 7 and a remainder of 370.
Write down 7 as next digit of the result. 
Result so far: 5173.837
Deduct 6930 from 7300 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 11:
3700 divided by 990 is 3 with a remainder of 730.
Record the quotient 3 as the next digit in the result. 
Result so far: 5173.8373
Deduct 2970 from 3700 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 12:
The number 990 fits into 7300 7 times, leaving a remainder of 370.
Record the quotient 7 as the next digit in the result. 
Result so far: 5173.83737
The remainder is 370 after subtracting 6930 from 7300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 13:
When dividing 3700 by 990, we get 3 with a remainder of 730.
The next digit of our result is 3. 
Result so far: 5173.837373
The remainder is 730 after subtracting 2970 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

Moving on to step 14:
The number 990 fits into 7300 7 times, leaving a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 5173.8373737
If we take 6930 away from 7300, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 15:
If we divide 3700 by 990, we get 3 and a remainder of 730.
The number 3 becomes the next digit in our result. 
Result so far: 5173.83737373
Deduct 2970 from 3700 and we're left with 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

After the division, we end up with 5173.83737373 and a remainder of 7.3e-07.
