We're dividing 4902748 by 308 
The aim is to understand the frequency of 308 in 4902748.

Let's proceed to step 1:
If we divide 4 by 308, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 308

On to step 2:
308 goes into 49 0 times with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 49 to get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 308

Going ahead to step 3:
When dividing 490 by 308, we get 1 with a remainder of 182.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 182 after subtracting 308 from 490.
Bring next digit (2) of the dividend behind the 182 and repeat the process: 1822 / 308

On to step 4:
308 can be fit into 1822 5 times, resulting in a remainder of 282.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 1540 from 1822 leaves us with 282.
Include the next digit (7) from the dividend after 282, then repeat: 2827 / 308

Advancing to step 5:
When dividing 2827 by 308, we get 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 159.0
If we take 2772 away from 2827, we end up with 55.
Take the next digit (4) from the dividend and append it to 55, then repeat: 554 / 308

Step 6:
308 can be fit into 554 1 times, resulting in a remainder of 246.
Write down 1 as next digit of the result. 
Result so far: 1591.0
The remainder is 246 after subtracting 308 from 554.
Take the next digit (8) from the dividend and append it to 246, then repeat: 2468 / 308

Step 7:
308 goes into 2468 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 15918.0
Deduct 2464 from 2468 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 308 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15918.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
The number 308 fits into 400 1 times, leaving a remainder of 92.
The number 1 becomes the next digit in our result. 
Result so far: 15918.01
If we take 308 away from 400, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 10:
308 goes into 920 2 times with a remainder of 304.
Write down 2 as next digit of the result. 
Result so far: 15918.012
The remainder is 304 after subtracting 616 from 920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 11:
308 goes into 3040 9 times with a remainder of 268.
Put 9 as the next digit of the answer. 
Result so far: 15918.0129
Subtracting 2772 from 3040 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Step 12:
If we divide 2680 by 308, we get 8 and a remainder of 216.
The next digit of our result is 8. 
Result so far: 15918.01298
If we take 2464 away from 2680, we end up with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Let's proceed to step 13:
308 goes into 2160 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 15918.012987
Deduct 2156 from 2160 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 14:
308 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 15918.012987
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 15:
When dividing 400 by 308, we get 1 with a remainder of 92.
Write down 1 as next digit of the result. 
Result so far: 15918.01298701
The remainder is 92 after subtracting 308 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Our division results in 15918.01298701 with a remaining 9.2e-08.
