We're dividing 1740060 by 309 
The aim is to understand the frequency of 309 in 1740060.

Step 1:
309 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 309

Moving on to step 2:
309 goes into 17 0 times with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 309

Let's proceed to step 3:
When dividing 174 by 309, we get 0 with a remainder of 174.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 174 to get 174.
Append the next digit (0) from the dividend to 174 and continue with: 1740 / 309

Advancing to step 4:
309 can be fit into 1740 5 times, resulting in a remainder of 195.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 1545 from 1740 and we're left with 195.
Grab the next digit (0) from the dividend, add it to 195, then carry on: 1950 / 309

Moving on to step 5:
When dividing 1950 by 309, we get 6 with a remainder of 96.
The next digit of our result is 6. 
Result so far: 56.0
If we take 1854 away from 1950, we end up with 96.
Take the next digit (6) from the dividend and append it to 96, then repeat: 966 / 309

Step 6:
If we divide 966 by 309, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 563.0
Subtracting 927 from 966 leaves us with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 309

Going ahead to step 7:
390 divided by 309 is 1 with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 5631.0
Subtracting 309 from 390 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
The number 309 fits into 810 2 times, leaving a remainder of 192.
Record the quotient 2 as the next digit in the result. 
Result so far: 5631.2
Subtract 618 from 810 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 9:
If we divide 1920 by 309, we get 6 and a remainder of 66.
Write down 6 as next digit of the result. 
Result so far: 5631.26
The remainder is 66 after subtracting 1854 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
309 can be fit into 660 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 5631.262
Subtracting 618 from 660 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 11:
420 divided by 309 is 1 with a remainder of 111.
Record the quotient 1 as the next digit in the result. 
Result so far: 5631.2621
Subtract 309 from 420 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 12:
When dividing 1110 by 309, we get 3 with a remainder of 183.
Use 3 as the next digit of our solution. 
Result so far: 5631.26213
If we subtract 927 from 1110, we get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Going ahead to step 13:
When dividing 1830 by 309, we get 5 with a remainder of 285.
Write down 5 as next digit of the result. 
Result so far: 5631.262135
Subtracting 1545 from 1830 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 14:
If we divide 2850 by 309, we get 9 and a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 5631.2621359
If we subtract 2781 from 2850, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 15:
309 can be fit into 690 2 times, resulting in a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 5631.26213592
The remainder is 72 after subtracting 618 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 5631.26213592 with a remaining 7.2e-08.
