We're dividing 74443056 by 309 
The aim is to understand the frequency of 309 in 74443056.

Going ahead to step 1:
The number 309 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 309

Going ahead to step 2:
309 can be fit into 74 0 times, resulting in a remainder of 74.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 309

Moving on to step 3:
If we divide 744 by 309, we get 2 and a remainder of 126.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 618 from 744 and we're left with 126.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 309

Step 4:
309 goes into 1264 4 times with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 1236 from 1264, we get 28.
Append the next digit (3) from the dividend to 28 and continue with: 283 / 309

On to step 5:
283 divided by 309 is 0 with a remainder of 283.
Write down 0 as next digit of the result. 
Result so far: 240.0
The remainder is 283 after subtracting 0 from 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 309

Going ahead to step 6:
309 goes into 2830 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 2409.0
Deduct 2781 from 2830 and we're left with 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 309

Step 7:
The number 309 fits into 495 1 times, leaving a remainder of 186.
The number 1 becomes the next digit in our result. 
Result so far: 24091.0
Subtracting 309 from 495 leaves us with 186.
Grab the next digit (6) from the dividend, add it to 186, then carry on: 1866 / 309

Advancing to step 8:
If we divide 1866 by 309, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 240916.0
If we subtract 1854 from 1866, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
When dividing 120 by 309, we get 0 with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 240916.0
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Advancing to step 10:
1200 divided by 309 is 3 with a remainder of 273.
Put 3 as the next digit of the answer. 
Result so far: 240916.03
Deduct 927 from 1200 and we're left with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Step 11:
2730 divided by 309 is 8 with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 240916.038
Subtracting 2472 from 2730 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Step 12:
309 goes into 2580 8 times with a remainder of 108.
Use 8 as the next digit of our solution. 
Result so far: 240916.0388
If we subtract 2472 from 2580, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

After the division, we end up with 240916.0388 and a remainder of 0.00108.
