Let's divide 27780990 by 204
The aim is to understand the frequency of 204 in 27780990.

Step 1:
If we divide 2 by 204, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 204

Advancing to step 2:
The number 204 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 204

Let's proceed to step 3:
The number 204 fits into 277 1 times, leaving a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 204 away from 277, we end up with 73.
Append the next digit (8) from the dividend to 73 and continue with: 738 / 204

On to step 4:
When dividing 738 by 204, we get 3 with a remainder of 126.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we subtract 612 from 738, we get 126.
Take the next digit (0) from the dividend and append it to 126, then repeat: 1260 / 204

Going ahead to step 5:
204 goes into 1260 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 136.0
Subtracting 1224 from 1260 leaves us with 36.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 204

Step 6:
If we divide 369 by 204, we get 1 and a remainder of 165.
The number 1 becomes the next digit in our result. 
Result so far: 1361.0
The remainder is 165 after subtracting 204 from 369.
Take the next digit (9) from the dividend and append it to 165, then repeat: 1659 / 204

Advancing to step 7:
If we divide 1659 by 204, we get 8 and a remainder of 27.
Put 8 as the next digit of the answer. 
Result so far: 13618.0
Subtract 1632 from 1659 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 204

Moving on to step 8:
When dividing 270 by 204, we get 1 with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 136181.0
Subtract 204 from 270 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 9:
The number 204 fits into 660 3 times, leaving a remainder of 48.
Use 3 as the next digit of our solution. 
Result so far: 136181.3
Subtracting 612 from 660 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 204, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 136181.32
If we subtract 408 from 480, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 11:
720 divided by 204 is 3 with a remainder of 108.
The next digit of our result is 3. 
Result so far: 136181.323
Subtracting 612 from 720 leaves us 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.

Step 12:
204 goes into 1080 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 136181.3235
The remainder is 60 after subtracting 1020 from 1080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 13:
When dividing 600 by 204, we get 2 with a remainder of 192.
Put 2 as the next digit of the answer. 
Result so far: 136181.32352
The remainder is 192 after subtracting 408 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 14:
The number 204 fits into 1920 9 times, leaving a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 136181.323529
The remainder is 84 after subtracting 1836 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Going ahead to step 15:
204 can be fit into 840 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 136181.3235294
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.

Step 16:
204 goes into 240 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 136181.32352941
Subtracting 204 from 240 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

After the division, we end up with 136181.32352941 and a remainder of 3.6e-08.
