41012521 ÷ 204 
The aim is to understand the frequency of 204 in 41012521.

Let's proceed to step 1:
204 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 204

Moving on to step 2:
204 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Include the next digit (0) from the dividend after 41, then repeat: 410 / 204

Moving on to step 3:
The number 204 fits into 410 2 times, leaving a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 408 away from 410, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 204

Going ahead to step 4:
The number 204 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 21 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 204

Moving on to step 5:
If we divide 212 by 204, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 201.0
The remainder is 8 after subtracting 204 from 212.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 204

Going ahead to step 6:
85 divided by 204 is 0 with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 2010.0
If we subtract 0 from 85, we get 85.
Take the next digit (2) from the dividend and append it to 85, then repeat: 852 / 204

Let's proceed to step 7:
204 goes into 852 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 20104.0
The remainder is 36 after subtracting 816 from 852.
Grab the next digit (1) from the dividend, add it to 36, then carry on: 361 / 204

Advancing to step 8:
When dividing 361 by 204, we get 1 with a remainder of 157.
Record the quotient 1 as the next digit in the result. 
Result so far: 201041.0
If we take 204 away from 361, we end up with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
1570 divided by 204 is 7 with a remainder of 142.
Put 7 as the next digit of the answer. 
Result so far: 201041.7
Deduct 1428 from 1570 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
204 goes into 1420 6 times with a remainder of 196.
Put 6 as the next digit of the answer. 
Result so far: 201041.76
Subtracting 1224 from 1420 leaves us with 196.
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:
When dividing 1960 by 204, we get 9 with a remainder of 124.
The number 9 becomes the next digit in our result. 
Result so far: 201041.769
The remainder is 124 after subtracting 1836 from 1960.
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:
204 can be fit into 1240 6 times, resulting in a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 201041.7696
Deduct 1224 from 1240 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
If we divide 160 by 204, we get 0 and a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 201041.7696
Deduct 0 from 160 and we're left 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.

Moving on to step 14:
204 goes into 1600 7 times with a remainder of 172.
Use 7 as the next digit of our solution. 
Result so far: 201041.769607
Deduct 1428 from 1600 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Let's proceed to step 15:
If we divide 1720 by 204, we get 8 and a remainder of 88.
The number 8 becomes the next digit in our result. 
Result so far: 201041.7696078
Subtracting 1632 from 1720 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 16:
880 divided by 204 is 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 201041.76960784
If we take 816 away from 880, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 201041.76960784 with a remainder of 6.4e-08.
