1998155 ÷ 303 
Our goal is to divide 1998155 by 303.

On to step 1:
1 divided by 303 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 303

Let's proceed to step 2:
19 divided by 303 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 303

On to step 3:
199 divided by 303 is 0 with a remainder of 199.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 199, we end up with 199.
Include the next digit (8) from the dividend after 199, then repeat: 1998 / 303

Let's proceed to step 4:
303 can be fit into 1998 6 times, resulting in a remainder of 180.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 1818 from 1998, we get 180.
Take the next digit (1) from the dividend and append it to 180, then repeat: 1801 / 303

Step 5:
1801 divided by 303 is 5 with a remainder of 286.
Write down 5 as next digit of the result. 
Result so far: 65.0
Subtract 1515 from 1801 to get 286.
Fetch the next digit (5) from the dividend, attach it to 286 and continue: 2865 / 303

Advancing to step 6:
If we divide 2865 by 303, we get 9 and a remainder of 138.
The number 9 becomes the next digit in our result. 
Result so far: 659.0
If we subtract 2727 from 2865, we get 138.
Include the next digit (5) from the dividend after 138, then repeat: 1385 / 303

Let's proceed to step 7:
1385 divided by 303 is 4 with a remainder of 173.
The number 4 becomes the next digit in our result. 
Result so far: 6594.0
Subtracting 1212 from 1385 leaves us with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Moving on to step 8:
If we divide 1730 by 303, we get 5 and a remainder of 215.
The number 5 becomes the next digit in our result. 
Result so far: 6594.5
If we take 1515 away from 1730, we end up with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 9:
If we divide 2150 by 303, we get 7 and a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 6594.57
If we subtract 2121 from 2150, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
When dividing 290 by 303, we get 0 with a remainder of 290.
Write down 0 as next digit of the result. 
Result so far: 6594.57
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 11:
303 can be fit into 2900 9 times, resulting in a remainder of 173.
Use 9 as the next digit of our solution. 
Result so far: 6594.5709
If we subtract 2727 from 2900, we get 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Step 12:
The number 303 fits into 1730 5 times, leaving a remainder of 215.
Put 5 as the next digit of the answer. 
Result so far: 6594.57095
If we subtract 1515 from 1730, we get 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 13:
303 can be fit into 2150 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 6594.570957
The remainder is 29 after subtracting 2121 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 14:
The number 303 fits into 290 0 times, leaving a remainder of 290.
Use 0 as the next digit of our solution. 
Result so far: 6594.570957
If we subtract 0 from 290, we get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 15:
When dividing 2900 by 303, we get 9 with a remainder of 173.
Write down 9 as next digit of the result. 
Result so far: 6594.57095709
Deduct 2727 from 2900 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

The final result is 6594.57095709 with a remainder of 1.73e-07.
