We're dividing 21129184 by 604 
Let's see how many times 604 fits into 21129184.

Advancing to step 1:
604 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 604

Advancing to step 2:
If we divide 21 by 604, we get 0 and a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 604

Let's proceed to step 3:
604 goes into 211 0 times with a remainder of 211.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 211 leaves us with 211.
Grab the next digit (2) from the dividend, add it to 211, then carry on: 2112 / 604

On to step 4:
When dividing 2112 by 604, we get 3 with a remainder of 300.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 1812 from 2112 and we're left with 300.
Fetch the next digit (9) from the dividend, attach it to 300 and continue: 3009 / 604

Moving on to step 5:
The number 604 fits into 3009 4 times, leaving a remainder of 593.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 2416 from 3009 leaves us with 593.
Fetch the next digit (1) from the dividend, attach it to 593 and continue: 5931 / 604

On to step 6:
When dividing 5931 by 604, we get 9 with a remainder of 495.
Put 9 as the next digit of the answer. 
Result so far: 349.0
If we take 5436 away from 5931, we end up with 495.
Take the next digit (8) from the dividend and append it to 495, then repeat: 4958 / 604

Advancing to step 7:
4958 divided by 604 is 8 with a remainder of 126.
The number 8 becomes the next digit in our result. 
Result so far: 3498.0
The remainder is 126 after subtracting 4832 from 4958.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 604

Going ahead to step 8:
604 goes into 1264 2 times with a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 34982.0
Deduct 1208 from 1264 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 9:
604 can be fit into 560 0 times, resulting in a remainder of 560.
The next digit of our result is 0. 
Result so far: 34982.0
If we take 0 away from 560, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 10:
The number 604 fits into 5600 9 times, leaving a remainder of 164.
Put 9 as the next digit of the answer. 
Result so far: 34982.09
Subtracting 5436 from 5600 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 11:
1640 divided by 604 is 2 with a remainder of 432.
The number 2 becomes the next digit in our result. 
Result so far: 34982.092
If we take 1208 away from 1640, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Let's proceed to step 12:
When dividing 4320 by 604, we get 7 with a remainder of 92.
Use 7 as the next digit of our solution. 
Result so far: 34982.0927
Subtract 4228 from 4320 to get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 13:
604 can be fit into 920 1 times, resulting in a remainder of 316.
Record the quotient 1 as the next digit in the result. 
Result so far: 34982.09271
Subtract 604 from 920 to get 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Let's proceed to step 14:
604 can be fit into 3160 5 times, resulting in a remainder of 140.
The next digit of our result is 5. 
Result so far: 34982.092715
If we take 3020 away from 3160, we end up with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

On to step 15:
604 goes into 1400 2 times with a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 34982.0927152
If we subtract 1208 from 1400, we get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Moving on to step 16:
604 can be fit into 1920 3 times, resulting in a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 34982.09271523
If we take 1812 away from 1920, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The quotient of the division is 34982.09271523, and the remainder is 1.08e-07.
