Let's divide 9902809 by 603
We want to figure out the number of times 9902809 can be divided by 603.

Moving on to step 1:
When dividing 9 by 603, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 603

Moving on to step 2:
If we divide 99 by 603, we get 0 and a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 99, we get 99.
Include the next digit (0) from the dividend after 99, then repeat: 990 / 603

Moving on to step 3:
990 divided by 603 is 1 with a remainder of 387.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 603 away from 990, we end up with 387.
Include the next digit (2) from the dividend after 387, then repeat: 3872 / 603

On to step 4:
3872 divided by 603 is 6 with a remainder of 254.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
The remainder is 254 after subtracting 3618 from 3872.
Take the next digit (8) from the dividend and append it to 254, then repeat: 2548 / 603

Going ahead to step 5:
When dividing 2548 by 603, we get 4 with a remainder of 136.
Write down 4 as next digit of the result. 
Result so far: 164.0
Subtract 2412 from 2548 to get 136.
Grab the next digit (0) from the dividend, add it to 136, then carry on: 1360 / 603

Advancing to step 6:
603 goes into 1360 2 times with a remainder of 154.
The next digit of our result is 2. 
Result so far: 1642.0
The remainder is 154 after subtracting 1206 from 1360.
Include the next digit (9) from the dividend after 154, then repeat: 1549 / 603

Advancing to step 7:
1549 divided by 603 is 2 with a remainder of 343.
Record the quotient 2 as the next digit in the result. 
Result so far: 16422.0
The remainder is 343 after subtracting 1206 from 1549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 8:
The number 603 fits into 3430 5 times, leaving a remainder of 415.
The number 5 becomes the next digit in our result. 
Result so far: 16422.5
The remainder is 415 after subtracting 3015 from 3430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Moving on to step 9:
The number 603 fits into 4150 6 times, leaving a remainder of 532.
Put 6 as the next digit of the answer. 
Result so far: 16422.56
If we take 3618 away from 4150, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Let's proceed to step 10:
5320 divided by 603 is 8 with a remainder of 496.
The next digit of our result is 8. 
Result so far: 16422.568
Subtract 4824 from 5320 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 11:
If we divide 4960 by 603, we get 8 and a remainder of 136.
The next digit of our result is 8. 
Result so far: 16422.5688
If we take 4824 away from 4960, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The quotient of the division is 16422.5688, and the remainder is 0.00136.
