We look at the division of 85082066 by 308 
The aim is to understand the frequency of 308 in 85082066.

Going ahead to step 1:
The number 308 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 308

Step 2:
When dividing 85 by 308, we get 0 with a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Take the next digit (0) from the dividend and append it to 85, then repeat: 850 / 308

Let's proceed to step 3:
The number 308 fits into 850 2 times, leaving a remainder of 234.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 616 from 850 to get 234.
Grab the next digit (8) from the dividend, add it to 234, then carry on: 2348 / 308

Going ahead to step 4:
2348 divided by 308 is 7 with a remainder of 192.
Put 7 as the next digit of the answer. 
Result so far: 27.0
If we subtract 2156 from 2348, we get 192.
Include the next digit (2) from the dividend after 192, then repeat: 1922 / 308

Advancing to step 5:
1922 divided by 308 is 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 276.0
Subtracting 1848 from 1922 leaves us with 74.
Grab the next digit (0) from the dividend, add it to 74, then carry on: 740 / 308

Going ahead to step 6:
If we divide 740 by 308, we get 2 and a remainder of 124.
The next digit of our result is 2. 
Result so far: 2762.0
If we take 616 away from 740, we end up with 124.
Bring next digit (6) of the dividend behind the 124 and repeat the process: 1246 / 308

Going ahead to step 7:
1246 divided by 308 is 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 27624.0
Deduct 1232 from 1246 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 308

Going ahead to step 8:
If we divide 146 by 308, we get 0 and a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 276240.0
If we take 0 away from 146, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 9:
308 goes into 1460 4 times with a remainder of 228.
The next digit of our result is 4. 
Result so far: 276240.4
Subtract 1232 from 1460 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Let's proceed to step 10:
308 goes into 2280 7 times with a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 276240.47
If we take 2156 away from 2280, we end up with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 11:
308 can be fit into 1240 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 276240.474
Subtracting 1232 from 1240 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
308 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 276240.474
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
The number 308 fits into 800 2 times, leaving a remainder of 184.
Record the quotient 2 as the next digit in the result. 
Result so far: 276240.47402
If we take 616 away from 800, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 14:
The number 308 fits into 1840 5 times, leaving a remainder of 300.
The next digit of our result is 5. 
Result so far: 276240.474025
The remainder is 300 after subtracting 1540 from 1840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 15:
When dividing 3000 by 308, we get 9 with a remainder of 228.
The number 9 becomes the next digit in our result. 
Result so far: 276240.4740259
The remainder is 228 after subtracting 2772 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 16:
The number 308 fits into 2280 7 times, leaving a remainder of 124.
Put 7 as the next digit of the answer. 
Result so far: 276240.47402597
The remainder is 124 after subtracting 2156 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 276240.47402597, with a leftover of 1.24e-07.
