Let's divide 21956456 by 303
We want to figure out the number of times 21956456 can be divided by 303.

On to step 1:
If we divide 2 by 303, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 303

Going ahead to step 2:
The number 303 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 303

Advancing to step 3:
303 goes into 219 0 times with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 219 after subtracting 0 from 219.
Fetch the next digit (5) from the dividend, attach it to 219 and continue: 2195 / 303

Moving on to step 4:
When dividing 2195 by 303, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 2121 from 2195 and we're left with 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 303

Going ahead to step 5:
When dividing 746 by 303, we get 2 with a remainder of 140.
The next digit of our result is 2. 
Result so far: 72.0
If we take 606 away from 746, we end up with 140.
Include the next digit (4) from the dividend after 140, then repeat: 1404 / 303

Let's proceed to step 6:
The number 303 fits into 1404 4 times, leaving a remainder of 192.
The number 4 becomes the next digit in our result. 
Result so far: 724.0
The remainder is 192 after subtracting 1212 from 1404.
Bring next digit (5) of the dividend behind the 192 and repeat the process: 1925 / 303

Step 7:
1925 divided by 303 is 6 with a remainder of 107.
Write down 6 as next digit of the result. 
Result so far: 7246.0
Deduct 1818 from 1925 and we're left with 107.
Bring next digit (6) of the dividend behind the 107 and repeat the process: 1076 / 303

On to step 8:
303 goes into 1076 3 times with a remainder of 167.
Put 3 as the next digit of the answer. 
Result so far: 72463.0
If we subtract 909 from 1076, we get 167.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1670, and continue the process.

On to step 9:
The number 303 fits into 1670 5 times, leaving a remainder of 155.
The number 5 becomes the next digit in our result. 
Result so far: 72463.5
If we subtract 1515 from 1670, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 10:
When dividing 1550 by 303, we get 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 72463.55
Deduct 1515 from 1550 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 72463.55 and a remainder of 0.035.
