Let's divide 71575176 by 308
The aim is to understand the frequency of 308 in 71575176.

Advancing to step 1:
7 divided by 308 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 308

Going ahead to step 2:
If we divide 71 by 308, we get 0 and a remainder of 71.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (5) from the dividend, attach it to 71 and continue: 715 / 308

Going ahead to step 3:
308 goes into 715 2 times with a remainder of 99.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 99 after subtracting 616 from 715.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 308

Advancing to step 4:
308 can be fit into 997 3 times, resulting in a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 924 from 997 and we're left with 73.
Fetch the next digit (5) from the dividend, attach it to 73 and continue: 735 / 308

Moving on to step 5:
308 can be fit into 735 2 times, resulting in a remainder of 119.
The next digit of our result is 2. 
Result so far: 232.0
Subtracting 616 from 735 leaves us with 119.
Grab the next digit (1) from the dividend, add it to 119, then carry on: 1191 / 308

Going ahead to step 6:
If we divide 1191 by 308, we get 3 and a remainder of 267.
Write down 3 as next digit of the result. 
Result so far: 2323.0
If we subtract 924 from 1191, we get 267.
Include the next digit (7) from the dividend after 267, then repeat: 2677 / 308

Advancing to step 7:
When dividing 2677 by 308, we get 8 with a remainder of 213.
Record the quotient 8 as the next digit in the result. 
Result so far: 23238.0
Subtract 2464 from 2677 to get 213.
Append the next digit (6) from the dividend to 213 and continue with: 2136 / 308

On to step 8:
The number 308 fits into 2136 6 times, leaving a remainder of 288.
The next digit of our result is 6. 
Result so far: 232386.0
If we subtract 1848 from 2136, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 9:
308 goes into 2880 9 times with a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 232386.9
If we subtract 2772 from 2880, we get 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
308 goes into 1080 3 times with a remainder of 156.
Put 3 as the next digit of the answer. 
Result so far: 232386.93
Subtracting 924 from 1080 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 11:
308 goes into 1560 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 232386.935
Deduct 1540 from 1560 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
The number 308 fits into 200 0 times, leaving a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 232386.935
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 13:
308 goes into 2000 6 times with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 232386.93506
The remainder is 152 after subtracting 1848 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 14:
The number 308 fits into 1520 4 times, leaving a remainder of 288.
The next digit of our result is 4. 
Result so far: 232386.935064
The remainder is 288 after subtracting 1232 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 15:
2880 divided by 308 is 9 with a remainder of 108.
The number 9 becomes the next digit in our result. 
Result so far: 232386.9350649
The remainder is 108 after subtracting 2772 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Advancing to step 16:
308 can be fit into 1080 3 times, resulting in a remainder of 156.
Write down 3 as next digit of the result. 
Result so far: 232386.93506493
If we subtract 924 from 1080, we get 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

In conclusion, the division gives 232386.93506493 with a balance of 1.56e-07.
