54830105 divided by 308 
The aim is to understand the frequency of 308 in 54830105.

On to step 1:
When dividing 5 by 308, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 308

Step 2:
308 can be fit into 54 0 times, resulting in a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Take the next digit (8) from the dividend and append it to 54, then repeat: 548 / 308

Step 3:
308 can be fit into 548 1 times, resulting in a remainder of 240.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 308 from 548, we get 240.
Bring next digit (3) of the dividend behind the 240 and repeat the process: 2403 / 308

Let's proceed to step 4:
If we divide 2403 by 308, we get 7 and a remainder of 247.
Put 7 as the next digit of the answer. 
Result so far: 17.0
The remainder is 247 after subtracting 2156 from 2403.
Include the next digit (0) from the dividend after 247, then repeat: 2470 / 308

Going ahead to step 5:
308 goes into 2470 8 times with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 178.0
Subtract 2464 from 2470 to get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 308

Advancing to step 6:
61 divided by 308 is 0 with a remainder of 61.
The next digit of our result is 0. 
Result so far: 1780.0
Deduct 0 from 61 and we're left with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 308

Moving on to step 7:
The number 308 fits into 610 1 times, leaving a remainder of 302.
The number 1 becomes the next digit in our result. 
Result so far: 17801.0
If we take 308 away from 610, we end up with 302.
Include the next digit (5) from the dividend after 302, then repeat: 3025 / 308

Going ahead to step 8:
The number 308 fits into 3025 9 times, leaving a remainder of 253.
The number 9 becomes the next digit in our result. 
Result so far: 178019.0
Subtract 2772 from 3025 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 9:
2530 divided by 308 is 8 with a remainder of 66.
Put 8 as the next digit of the answer. 
Result so far: 178019.8
The remainder is 66 after subtracting 2464 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
The number 308 fits into 660 2 times, leaving a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 178019.82
If we take 616 away from 660, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
If we divide 440 by 308, we get 1 and a remainder of 132.
Write down 1 as next digit of the result. 
Result so far: 178019.821
Subtracting 308 from 440 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 12:
308 can be fit into 1320 4 times, resulting in a remainder of 88.
The next digit of our result is 4. 
Result so far: 178019.8214
Deduct 1232 from 1320 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 13:
When dividing 880 by 308, we get 2 with a remainder of 264.
Write down 2 as next digit of the result. 
Result so far: 178019.82142
The remainder is 264 after subtracting 616 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Moving on to step 14:
308 can be fit into 2640 8 times, resulting in a remainder of 176.
Record the quotient 8 as the next digit in the result. 
Result so far: 178019.821428
The remainder is 176 after subtracting 2464 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 15:
The number 308 fits into 1760 5 times, leaving a remainder of 220.
Use 5 as the next digit of our solution. 
Result so far: 178019.8214285
The remainder is 220 after subtracting 1540 from 1760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 16:
308 goes into 2200 7 times with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 178019.82142857
Subtract 2156 from 2200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 178019.82142857 and a remainder of 4.4e-08.
