3890872 ÷ 204 
The aim is to understand the frequency of 204 in 3890872.

Moving on to step 1:
204 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 204

Moving on to step 2:
38 divided by 204 is 0 with a remainder of 38.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 204

Let's proceed to step 3:
When dividing 389 by 204, we get 1 with a remainder of 185.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 204 from 389 to get 185.
Append the next digit (0) from the dividend to 185 and continue with: 1850 / 204

Let's proceed to step 4:
204 can be fit into 1850 9 times, resulting in a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 1836 from 1850, we get 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 204

Step 5:
If we divide 148 by 204, we get 0 and a remainder of 148.
Write down 0 as next digit of the result. 
Result so far: 190.0
Subtracting 0 from 148 leaves us with 148.
Bring next digit (7) of the dividend behind the 148 and repeat the process: 1487 / 204

On to step 6:
1487 divided by 204 is 7 with a remainder of 59.
Put 7 as the next digit of the answer. 
Result so far: 1907.0
If we subtract 1428 from 1487, we get 59.
Take the next digit (2) from the dividend and append it to 59, then repeat: 592 / 204

Moving on to step 7:
204 goes into 592 2 times with a remainder of 184.
The next digit of our result is 2. 
Result so far: 19072.0
If we subtract 408 from 592, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 8:
The number 204 fits into 1840 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 19072.9
If we subtract 1836 from 1840, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
40 divided by 204 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 19072.9
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
204 goes into 400 1 times with a remainder of 196.
Write down 1 as next digit of the result. 
Result so far: 19072.901
The remainder is 196 after subtracting 204 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

On to step 11:
204 goes into 1960 9 times with a remainder of 124.
Put 9 as the next digit of the answer. 
Result so far: 19072.9019
If we take 1836 away from 1960, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 12:
If we divide 1240 by 204, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 19072.90196
The remainder is 16 after subtracting 1224 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
160 divided by 204 is 0 with a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 19072.90196
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
204 goes into 1600 7 times with a remainder of 172.
Record the quotient 7 as the next digit in the result. 
Result so far: 19072.9019607
The remainder is 172 after subtracting 1428 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 15:
When dividing 1720 by 204, we get 8 with a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 19072.90196078
The remainder is 88 after subtracting 1632 from 1720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

In conclusion, the division gives 19072.90196078 with a balance of 8.8e-08.
