Let's divide 303521 by 14
Our goal is to divide 303521 by 14.

Going ahead to step 1:
14 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 14

Advancing to step 2:
If we divide 30 by 14, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 28 from 30, we get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 14

Moving on to step 3:
When dividing 23 by 14, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 14 from 23 to get 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 14

Advancing to step 4:
If we divide 95 by 14, we get 6 and a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 216.0
If we subtract 84 from 95, we get 11.
Grab the next digit (2) from the dividend, add it to 11, then carry on: 112 / 14

Going ahead to step 5:
112 divided by 14 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 2168.0
If we subtract 112 from 112, we get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 14

Step 6:
When dividing 1 by 14, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 21680.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 14, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 21680.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
14 can be fit into 100 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 21680.07
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
14 goes into 20 1 times with a remainder of 6.
The next digit of our result is 1. 
Result so far: 21680.071
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 14 fits into 60 4 times, leaving a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 21680.0714
If we subtract 56 from 60, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
14 goes into 40 2 times with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 21680.07142
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
120 divided by 14 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 21680.071428
If we subtract 112 from 120, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 14 is 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 21680.0714285
Subtracting 70 from 80 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
14 goes into 100 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 21680.07142857
If we take 98 away from 100, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 21680.07142857 with a remainder of 2e-09.
