We divide 28868172 by 308
The aim is to understand the frequency of 308 in 28868172.

On to step 1:
2 divided by 308 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 308

On to step 2:
If we divide 28 by 308, we get 0 and a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 308

Going ahead to step 3:
The number 308 fits into 288 0 times, leaving a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 288 and we're left with 288.
Bring next digit (6) of the dividend behind the 288 and repeat the process: 2886 / 308

Let's proceed to step 4:
2886 divided by 308 is 9 with a remainder of 114.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 2772 from 2886, we get 114.
Include the next digit (8) from the dividend after 114, then repeat: 1148 / 308

On to step 5:
When dividing 1148 by 308, we get 3 with a remainder of 224.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we take 924 away from 1148, we end up with 224.
Append the next digit (1) from the dividend to 224 and continue with: 2241 / 308

Going ahead to step 6:
The number 308 fits into 2241 7 times, leaving a remainder of 85.
Put 7 as the next digit of the answer. 
Result so far: 937.0
Deduct 2156 from 2241 and we're left with 85.
Append the next digit (7) from the dividend to 85 and continue with: 857 / 308

Advancing to step 7:
857 divided by 308 is 2 with a remainder of 241.
The next digit of our result is 2. 
Result so far: 9372.0
Subtract 616 from 857 to get 241.
Grab the next digit (2) from the dividend, add it to 241, then carry on: 2412 / 308

Going ahead to step 8:
2412 divided by 308 is 7 with a remainder of 256.
Use 7 as the next digit of our solution. 
Result so far: 93727.0
Deduct 2156 from 2412 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 9:
2560 divided by 308 is 8 with a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 93727.8
The remainder is 96 after subtracting 2464 from 2560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 10:
When dividing 960 by 308, we get 3 with a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 93727.83
The remainder is 36 after subtracting 924 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 11:
The number 308 fits into 360 1 times, leaving a remainder of 52.
The next digit of our result is 1. 
Result so far: 93727.831
If we subtract 308 from 360, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 12:
When dividing 520 by 308, we get 1 with a remainder of 212.
Write down 1 as next digit of the result. 
Result so far: 93727.8311
Subtract 308 from 520 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

After the division, we end up with 93727.8311 and a remainder of 0.00212.
