We look at the division of 30000021 by 604 
We're looking to find how many times 604 goes into 30000021.

On to step 1:
3 divided by 604 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 604

On to step 2:
30 divided by 604 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 604

Going ahead to step 3:
300 divided by 604 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 300 leaves us with 300.
Append the next digit (0) from the dividend to 300 and continue with: 3000 / 604

Moving on to step 4:
If we divide 3000 by 604, we get 4 and a remainder of 584.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 2416 away from 3000, we end up with 584.
Include the next digit (0) from the dividend after 584, then repeat: 5840 / 604

Advancing to step 5:
604 goes into 5840 9 times with a remainder of 404.
Write down 9 as next digit of the result. 
Result so far: 49.0
Deduct 5436 from 5840 and we're left with 404.
Include the next digit (0) from the dividend after 404, then repeat: 4040 / 604

On to step 6:
When dividing 4040 by 604, we get 6 with a remainder of 416.
Record the quotient 6 as the next digit in the result. 
Result so far: 496.0
Subtracting 3624 from 4040 leaves us with 416.
Take the next digit (2) from the dividend and append it to 416, then repeat: 4162 / 604

On to step 7:
When dividing 4162 by 604, we get 6 with a remainder of 538.
Record the quotient 6 as the next digit in the result. 
Result so far: 4966.0
If we subtract 3624 from 4162, we get 538.
Append the next digit (1) from the dividend to 538 and continue with: 5381 / 604

Let's proceed to step 8:
5381 divided by 604 is 8 with a remainder of 549.
The next digit of our result is 8. 
Result so far: 49668.0
If we take 4832 away from 5381, we end up with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 9:
If we divide 5490 by 604, we get 9 and a remainder of 54.
Write down 9 as next digit of the result. 
Result so far: 49668.9
The remainder is 54 after subtracting 5436 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 10:
If we divide 540 by 604, we get 0 and a remainder of 540.
Put 0 as the next digit of the answer. 
Result so far: 49668.9
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 11:
If we divide 5400 by 604, we get 8 and a remainder of 568.
The number 8 becomes the next digit in our result. 
Result so far: 49668.908
Subtracting 4832 from 5400 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

On to step 12:
604 can be fit into 5680 9 times, resulting in a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 49668.9089
Deduct 5436 from 5680 and we're left with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 13:
2440 divided by 604 is 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 49668.90894
Deduct 2416 from 2440 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 14:
If we divide 240 by 604, we get 0 and a remainder of 240.
The next digit of our result is 0. 
Result so far: 49668.90894
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 15:
If we divide 2400 by 604, we get 3 and a remainder of 588.
Write down 3 as next digit of the result. 
Result so far: 49668.9089403
Subtracting 1812 from 2400 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Going ahead to step 16:
When dividing 5880 by 604, we get 9 with a remainder of 444.
The number 9 becomes the next digit in our result. 
Result so far: 49668.90894039
The remainder is 444 after subtracting 5436 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

After the division, we end up with 49668.90894039 and a remainder of 4.44e-07.
