Let's divide 30420874 by 204
The aim is to understand the frequency of 204 in 30420874.

Step 1:
3 divided by 204 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 204

Going ahead to step 2:
204 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Bring next digit (4) of the dividend behind the 30 and repeat the process: 304 / 204

Step 3:
The number 204 fits into 304 1 times, leaving a remainder of 100.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 100 after subtracting 204 from 304.
Append the next digit (2) from the dividend to 100 and continue with: 1002 / 204

On to step 4:
When dividing 1002 by 204, we get 4 with a remainder of 186.
The next digit of our result is 4. 
Result so far: 14.0
The remainder is 186 after subtracting 816 from 1002.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 204

Step 5:
If we divide 1860 by 204, we get 9 and a remainder of 24.
The next digit of our result is 9. 
Result so far: 149.0
Deduct 1836 from 1860 and we're left with 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 204

Advancing to step 6:
204 goes into 248 1 times with a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 1491.0
Subtract 204 from 248 to get 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 204

Let's proceed to step 7:
447 divided by 204 is 2 with a remainder of 39.
Use 2 as the next digit of our solution. 
Result so far: 14912.0
Deduct 408 from 447 and we're left with 39.
Bring next digit (4) of the dividend behind the 39 and repeat the process: 394 / 204

Moving on to step 8:
394 divided by 204 is 1 with a remainder of 190.
Record the quotient 1 as the next digit in the result. 
Result so far: 149121.0
If we take 204 away from 394, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Advancing to step 9:
204 can be fit into 1900 9 times, resulting in a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 149121.9
If we subtract 1836 from 1900, we 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.

Going ahead to step 10:
204 goes into 640 3 times with a remainder of 28.
Use 3 as the next digit of our solution. 
Result so far: 149121.93
Deduct 612 from 640 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
280 divided by 204 is 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 149121.931
If we take 204 away from 280, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 12:
204 goes into 760 3 times with a remainder of 148.
The number 3 becomes the next digit in our result. 
Result so far: 149121.9313
If we subtract 612 from 760, we get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Advancing to step 13:
204 can be fit into 1480 7 times, resulting in a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 149121.93137
Deduct 1428 from 1480 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 14:
When dividing 520 by 204, we get 2 with a remainder of 112.
The next digit of our result is 2. 
Result so far: 149121.931372
If we take 408 away from 520, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
If we divide 1120 by 204, we get 5 and a remainder of 100.
Record the quotient 5 as the next digit in the result. 
Result so far: 149121.9313725
If we take 1020 away from 1120, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 16:
The number 204 fits into 1000 4 times, leaving a remainder of 184.
Put 4 as the next digit of the answer. 
Result so far: 149121.93137254
The remainder is 184 after subtracting 816 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Our division results in 149121.93137254 with a remaining 1.84e-07.
