3930749 ÷ 204 
The aim is to understand the frequency of 204 in 3930749.

Advancing to step 1:
The number 204 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 204

Going ahead to step 2:
204 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 204

On to step 3:
393 divided by 204 is 1 with a remainder of 189.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 204 from 393, we get 189.
Append the next digit (0) from the dividend to 189 and continue with: 1890 / 204

Step 4:
The number 204 fits into 1890 9 times, leaving a remainder of 54.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 1836 from 1890 and we're left with 54.
Append the next digit (7) from the dividend to 54 and continue with: 547 / 204

Let's proceed to step 5:
When dividing 547 by 204, we get 2 with a remainder of 139.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
Deduct 408 from 547 and we're left with 139.
Fetch the next digit (4) from the dividend, attach it to 139 and continue: 1394 / 204

Step 6:
204 goes into 1394 6 times with a remainder of 170.
Write down 6 as next digit of the result. 
Result so far: 1926.0
The remainder is 170 after subtracting 1224 from 1394.
Include the next digit (9) from the dividend after 170, then repeat: 1709 / 204

On to step 7:
If we divide 1709 by 204, we get 8 and a remainder of 77.
The number 8 becomes the next digit in our result. 
Result so far: 19268.0
If we subtract 1632 from 1709, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Let's proceed to step 8:
The number 204 fits into 770 3 times, leaving a remainder of 158.
Put 3 as the next digit of the answer. 
Result so far: 19268.3
Subtract 612 from 770 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 9:
204 goes into 1580 7 times with a remainder of 152.
The number 7 becomes the next digit in our result. 
Result so far: 19268.37
Subtracting 1428 from 1580 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 10:
The number 204 fits into 1520 7 times, leaving a remainder of 92.
The next digit of our result is 7. 
Result so far: 19268.377
If we subtract 1428 from 1520, we get 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final outcome is 19268.377, with a leftover of 0.0092.
