Let's divide 21423783 by 204
We're looking to find how many times 204 goes into 21423783.

Step 1:
The number 204 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 204

Going ahead to step 2:
21 divided by 204 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 204

Let's proceed to step 3:
214 divided by 204 is 1 with a remainder of 10.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 204 from 214 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 204

Step 4:
If we divide 102 by 204, we get 0 and a remainder of 102.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 102 leaves us with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 204

Let's proceed to step 5:
The number 204 fits into 1023 5 times, leaving a remainder of 3.
The next digit of our result is 5. 
Result so far: 105.0
Deduct 1020 from 1023 and we're left with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 204

Moving on to step 6:
204 goes into 37 0 times with a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 1050.0
If we subtract 0 from 37, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 204

Step 7:
378 divided by 204 is 1 with a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 10501.0
If we subtract 204 from 378, we get 174.
Grab the next digit (3) from the dividend, add it to 174, then carry on: 1743 / 204

Moving on to step 8:
204 goes into 1743 8 times with a remainder of 111.
Write down 8 as next digit of the result. 
Result so far: 105018.0
The remainder is 111 after subtracting 1632 from 1743.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Step 9:
The number 204 fits into 1110 5 times, leaving a remainder of 90.
The number 5 becomes the next digit in our result. 
Result so far: 105018.5
Deduct 1020 from 1110 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
204 goes into 900 4 times with a remainder of 84.
Put 4 as the next digit of the answer. 
Result so far: 105018.54
If we take 816 away from 900, we end up with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 11:
The number 204 fits into 840 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 105018.544
Subtract 816 from 840 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 105018.544 with a balance of 0.0024.
