6386771 divided by 204 
The aim is to understand the frequency of 204 in 6386771.

Let's proceed to step 1:
If we divide 6 by 204, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 204

Let's proceed to step 2:
63 divided by 204 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Append the next digit (8) from the dividend to 63 and continue with: 638 / 204

Let's proceed to step 3:
204 can be fit into 638 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 26 after subtracting 612 from 638.
Append the next digit (6) from the dividend to 26 and continue with: 266 / 204

Advancing to step 4:
If we divide 266 by 204, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 31.0
Subtract 204 from 266 to get 62.
Fetch the next digit (7) from the dividend, attach it to 62 and continue: 627 / 204

On to step 5:
The number 204 fits into 627 3 times, leaving a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 313.0
Subtract 612 from 627 to get 15.
Fetch the next digit (7) from the dividend, attach it to 15 and continue: 157 / 204

Going ahead to step 6:
157 divided by 204 is 0 with a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 3130.0
Subtract 0 from 157 to get 157.
Fetch the next digit (1) from the dividend, attach it to 157 and continue: 1571 / 204

Let's proceed to step 7:
204 can be fit into 1571 7 times, resulting in a remainder of 143.
Use 7 as the next digit of our solution. 
Result so far: 31307.0
Subtracting 1428 from 1571 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

On to step 8:
204 goes into 1430 7 times with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 31307.7
If we subtract 1428 from 1430, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
When dividing 20 by 204, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 31307.7
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 204 fits into 200 0 times, leaving a remainder of 200.
The next digit of our result is 0. 
Result so far: 31307.7
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 31307.7 with a remainder of 0.02.
