6503317 divided by 309 
The aim is to understand the frequency of 309 in 6503317.

On to step 1:
When dividing 6 by 309, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 309

Let's proceed to step 2:
The number 309 fits into 65 0 times, leaving a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Include the next digit (0) from the dividend after 65, then repeat: 650 / 309

Step 3:
650 divided by 309 is 2 with a remainder of 32.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 618 from 650 leaves us with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 309

Moving on to step 4:
309 can be fit into 323 1 times, resulting in a remainder of 14.
The next digit of our result is 1. 
Result so far: 21.0
Deduct 309 from 323 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 309

On to step 5:
309 can be fit into 143 0 times, resulting in a remainder of 143.
The next digit of our result is 0. 
Result so far: 210.0
Subtract 0 from 143 to get 143.
Append the next digit (1) from the dividend to 143 and continue with: 1431 / 309

On to step 6:
If we divide 1431 by 309, we get 4 and a remainder of 195.
Write down 4 as next digit of the result. 
Result so far: 2104.0
Subtract 1236 from 1431 to get 195.
Bring next digit (7) of the dividend behind the 195 and repeat the process: 1957 / 309

Going ahead to step 7:
309 can be fit into 1957 6 times, resulting in a remainder of 103.
Put 6 as the next digit of the answer. 
Result so far: 21046.0
If we take 1854 away from 1957, we end up with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Moving on to step 8:
The number 309 fits into 1030 3 times, leaving a remainder of 103.
Put 3 as the next digit of the answer. 
Result so far: 21046.3
Subtracting 927 from 1030 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Step 9:
309 goes into 1030 3 times with a remainder of 103.
The next digit of our result is 3. 
Result so far: 21046.33
Subtract 927 from 1030 to get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

The quotient of the division is 21046.33, and the remainder is 0.103.
