Let's divide 21400490 by 304
Our goal is to divide 21400490 by 304.

Moving on to step 1:
304 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 304

Advancing to step 2:
304 goes into 21 0 times with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 304

Advancing to step 3:
214 divided by 304 is 0 with a remainder of 214.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 214 to get 214.
Include the next digit (0) from the dividend after 214, then repeat: 2140 / 304

Let's proceed to step 4:
If we divide 2140 by 304, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 12 after subtracting 2128 from 2140.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 304

Let's proceed to step 5:
304 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 70.0
Subtracting 0 from 120 leaves us with 120.
Bring next digit (4) of the dividend behind the 120 and repeat the process: 1204 / 304

Advancing to step 6:
1204 divided by 304 is 3 with a remainder of 292.
Put 3 as the next digit of the answer. 
Result so far: 703.0
Deduct 912 from 1204 and we're left with 292.
Include the next digit (9) from the dividend after 292, then repeat: 2929 / 304

Let's proceed to step 7:
When dividing 2929 by 304, we get 9 with a remainder of 193.
The number 9 becomes the next digit in our result. 
Result so far: 7039.0
Subtracting 2736 from 2929 leaves us with 193.
Bring next digit (0) of the dividend behind the 193 and repeat the process: 1930 / 304

On to step 8:
The number 304 fits into 1930 6 times, leaving a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 70396.0
Subtracting 1824 from 1930 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Let's proceed to step 9:
When dividing 1060 by 304, we get 3 with a remainder of 148.
Use 3 as the next digit of our solution. 
Result so far: 70396.3
Deduct 912 from 1060 and we're left with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Moving on to step 10:
1480 divided by 304 is 4 with a remainder of 264.
Record the quotient 4 as the next digit in the result. 
Result so far: 70396.34
If we subtract 1216 from 1480, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 11:
If we divide 2640 by 304, we get 8 and a remainder of 208.
The number 8 becomes the next digit in our result. 
Result so far: 70396.348
If we subtract 2432 from 2640, we get 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Moving on to step 12:
The number 304 fits into 2080 6 times, leaving a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 70396.3486
Subtract 1824 from 2080 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Going ahead to step 13:
If we divide 2560 by 304, we get 8 and a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 70396.34868
If we subtract 2432 from 2560, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Advancing to step 14:
1280 divided by 304 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 70396.348684
Subtract 1216 from 1280 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 15:
304 can be fit into 640 2 times, resulting in a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 70396.3486842
The remainder is 32 after subtracting 608 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
The number 304 fits into 320 1 times, leaving a remainder of 16.
The next digit of our result is 1. 
Result so far: 70396.34868421
Subtract 304 from 320 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 70396.34868421, and the remainder is 1.6e-08.
