We divide 21304099 by 284
Our goal is to divide 21304099 by 284.

Step 1:
When dividing 2 by 284, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 284

Let's proceed to step 2:
284 can be fit into 21 0 times, resulting in a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (3) from the dividend after 21, then repeat: 213 / 284

Moving on to step 3:
When dividing 213 by 284, we get 0 with a remainder of 213.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 213, we end up with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 284

Going ahead to step 4:
The number 284 fits into 2130 7 times, leaving a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 1988 from 2130 to get 142.
Append the next digit (4) from the dividend to 142 and continue with: 1424 / 284

Moving on to step 5:
The number 284 fits into 1424 5 times, leaving a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 75.0
Deduct 1420 from 1424 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 284

Moving on to step 6:
If we divide 40 by 284, we get 0 and a remainder of 40.
The next digit of our result is 0. 
Result so far: 750.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 284

Step 7:
284 goes into 409 1 times with a remainder of 125.
Put 1 as the next digit of the answer. 
Result so far: 7501.0
If we take 284 away from 409, we end up with 125.
Include the next digit (9) from the dividend after 125, then repeat: 1259 / 284

Step 8:
If we divide 1259 by 284, we get 4 and a remainder of 123.
The number 4 becomes the next digit in our result. 
Result so far: 75014.0
Deduct 1136 from 1259 and we're left with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 9:
If we divide 1230 by 284, we get 4 and a remainder of 94.
Put 4 as the next digit of the answer. 
Result so far: 75014.4
Subtracting 1136 from 1230 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Moving on to step 10:
940 divided by 284 is 3 with a remainder of 88.
Use 3 as the next digit of our solution. 
Result so far: 75014.43
If we take 852 away from 940, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 11:
284 goes into 880 3 times with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 75014.433
The remainder is 28 after subtracting 852 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 75014.433 and a remainder of 0.0028.
