38088483 divided by 309 
The aim is to understand the frequency of 309 in 38088483.

Going ahead to step 1:
309 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 309

Going ahead to step 2:
309 goes into 38 0 times with a remainder of 38.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 309

Let's proceed to step 3:
309 goes into 380 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 309 from 380 to get 71.
Include the next digit (8) from the dividend after 71, then repeat: 718 / 309

Moving on to step 4:
309 goes into 718 2 times with a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 618 from 718 to get 100.
Include the next digit (8) from the dividend after 100, then repeat: 1008 / 309

Step 5:
309 can be fit into 1008 3 times, resulting in a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Deduct 927 from 1008 and we're left with 81.
Include the next digit (4) from the dividend after 81, then repeat: 814 / 309

Let's proceed to step 6:
The number 309 fits into 814 2 times, leaving a remainder of 196.
Use 2 as the next digit of our solution. 
Result so far: 1232.0
If we subtract 618 from 814, we get 196.
Include the next digit (8) from the dividend after 196, then repeat: 1968 / 309

Moving on to step 7:
When dividing 1968 by 309, we get 6 with a remainder of 114.
Record the quotient 6 as the next digit in the result. 
Result so far: 12326.0
If we subtract 1854 from 1968, we get 114.
Grab the next digit (3) from the dividend, add it to 114, then carry on: 1143 / 309

Step 8:
309 can be fit into 1143 3 times, resulting in a remainder of 216.
Put 3 as the next digit of the answer. 
Result so far: 123263.0
Subtract 927 from 1143 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

On to step 9:
309 can be fit into 2160 6 times, resulting in a remainder of 306.
Record the quotient 6 as the next digit in the result. 
Result so far: 123263.6
Subtract 1854 from 2160 to get 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 10:
3060 divided by 309 is 9 with a remainder of 279.
The next digit of our result is 9. 
Result so far: 123263.69
Deduct 2781 from 3060 and we're left with 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

Going ahead to step 11:
309 goes into 2790 9 times with a remainder of 9.
Record the quotient 9 as the next digit in the result. 
Result so far: 123263.699
If we subtract 2781 from 2790, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The quotient of the division is 123263.699, and the remainder is 0.0009.
