We're dividing 83741529 by 204 
The aim is to understand the frequency of 204 in 83741529.

On to step 1:
When dividing 8 by 204, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 204

Moving on to step 2:
204 goes into 83 0 times with a remainder of 83.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Take the next digit (7) from the dividend and append it to 83, then repeat: 837 / 204

Moving on to step 3:
When dividing 837 by 204, we get 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 816 from 837, we get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 204

On to step 4:
204 can be fit into 214 1 times, resulting in a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtract 204 from 214 to get 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 204

Going ahead to step 5:
The number 204 fits into 101 0 times, leaving a remainder of 101.
Put 0 as the next digit of the answer. 
Result so far: 410.0
The remainder is 101 after subtracting 0 from 101.
Bring next digit (5) of the dividend behind the 101 and repeat the process: 1015 / 204

Advancing to step 6:
The number 204 fits into 1015 4 times, leaving a remainder of 199.
The number 4 becomes the next digit in our result. 
Result so far: 4104.0
Subtract 816 from 1015 to get 199.
Take the next digit (2) from the dividend and append it to 199, then repeat: 1992 / 204

Step 7:
204 goes into 1992 9 times with a remainder of 156.
Record the quotient 9 as the next digit in the result. 
Result so far: 41049.0
Subtracting 1836 from 1992 leaves us with 156.
Grab the next digit (9) from the dividend, add it to 156, then carry on: 1569 / 204

Let's proceed to step 8:
204 can be fit into 1569 7 times, resulting in a remainder of 141.
Use 7 as the next digit of our solution. 
Result so far: 410497.0
If we subtract 1428 from 1569, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Let's proceed to step 9:
204 can be fit into 1410 6 times, resulting in a remainder of 186.
Record the quotient 6 as the next digit in the result. 
Result so far: 410497.6
If we subtract 1224 from 1410, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

On to step 10:
The number 204 fits into 1860 9 times, leaving a remainder of 24.
The next digit of our result is 9. 
Result so far: 410497.69
Deduct 1836 from 1860 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 11:
If we divide 240 by 204, we get 1 and a remainder of 36.
The next digit of our result is 1. 
Result so far: 410497.691
Deduct 204 from 240 and we're left 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.

Moving on to step 12:
204 goes into 360 1 times with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 410497.6911
Subtract 204 from 360 to get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

The final result is 410497.6911 with a remainder of 0.00156.
