We're dividing 4960202 by 309 
The aim is to understand the frequency of 309 in 4960202.

Advancing to step 1:
309 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 309

On to step 2:
If we divide 49 by 309, we get 0 and a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Grab the next digit (6) from the dividend, add it to 49, then carry on: 496 / 309

On to step 3:
309 can be fit into 496 1 times, resulting in a remainder of 187.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 309 from 496 leaves us with 187.
Include the next digit (0) from the dividend after 187, then repeat: 1870 / 309

On to step 4:
1870 divided by 309 is 6 with a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 16.0
The remainder is 16 after subtracting 1854 from 1870.
Include the next digit (2) from the dividend after 16, then repeat: 162 / 309

Let's proceed to step 5:
309 goes into 162 0 times with a remainder of 162.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we subtract 0 from 162, we get 162.
Bring next digit (0) of the dividend behind the 162 and repeat the process: 1620 / 309

Let's proceed to step 6:
The number 309 fits into 1620 5 times, leaving a remainder of 75.
The next digit of our result is 5. 
Result so far: 1605.0
Subtract 1545 from 1620 to get 75.
Grab the next digit (2) from the dividend, add it to 75, then carry on: 752 / 309

Step 7:
The number 309 fits into 752 2 times, leaving a remainder of 134.
Put 2 as the next digit of the answer. 
Result so far: 16052.0
If we take 618 away from 752, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 8:
When dividing 1340 by 309, we get 4 with a remainder of 104.
Put 4 as the next digit of the answer. 
Result so far: 16052.4
Deduct 1236 from 1340 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 9:
The number 309 fits into 1040 3 times, leaving a remainder of 113.
Record the quotient 3 as the next digit in the result. 
Result so far: 16052.43
Subtract 927 from 1040 to get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 10:
The number 309 fits into 1130 3 times, leaving a remainder of 203.
Write down 3 as next digit of the result. 
Result so far: 16052.433
If we subtract 927 from 1130, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Our division results in 16052.433 with a remaining 0.0203.
