We're dividing 30202153 by 991 
Our goal is to divide 30202153 by 991.

Step 1:
If we divide 3 by 991, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 991

On to step 2:
991 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 991

Let's proceed to step 3:
302 divided by 991 is 0 with a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 302 to get 302.
Fetch the next digit (0) from the dividend, attach it to 302 and continue: 3020 / 991

On to step 4:
991 can be fit into 3020 3 times, resulting in a remainder of 47.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 2973 from 3020, we get 47.
Take the next digit (2) from the dividend and append it to 47, then repeat: 472 / 991

Let's proceed to step 5:
472 divided by 991 is 0 with a remainder of 472.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtracting 0 from 472 leaves us with 472.
Bring next digit (1) of the dividend behind the 472 and repeat the process: 4721 / 991

Moving on to step 6:
991 can be fit into 4721 4 times, resulting in a remainder of 757.
Use 4 as the next digit of our solution. 
Result so far: 304.0
If we subtract 3964 from 4721, we get 757.
Take the next digit (5) from the dividend and append it to 757, then repeat: 7575 / 991

Advancing to step 7:
The number 991 fits into 7575 7 times, leaving a remainder of 638.
Write down 7 as next digit of the result. 
Result so far: 3047.0
The remainder is 638 after subtracting 6937 from 7575.
Include the next digit (3) from the dividend after 638, then repeat: 6383 / 991

Let's proceed to step 8:
The number 991 fits into 6383 6 times, leaving a remainder of 437.
Put 6 as the next digit of the answer. 
Result so far: 30476.0
If we take 5946 away from 6383, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 9:
The number 991 fits into 4370 4 times, leaving a remainder of 406.
Write down 4 as next digit of the result. 
Result so far: 30476.4
Subtracting 3964 from 4370 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

On to step 10:
If we divide 4060 by 991, we get 4 and a remainder of 96.
The number 4 becomes the next digit in our result. 
Result so far: 30476.44
Deduct 3964 from 4060 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

The quotient of the division is 30476.44, and the remainder is 0.096.
