Let's divide 2500900 by 308
The aim is to understand the frequency of 308 in 2500900.

Step 1:
2 divided by 308 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 308

Advancing to step 2:
25 divided by 308 is 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (0) from the dividend after 25, then repeat: 250 / 308

Step 3:
308 goes into 250 0 times with a remainder of 250.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 250 to get 250.
Grab the next digit (0) from the dividend, add it to 250, then carry on: 2500 / 308

Going ahead to step 4:
2500 divided by 308 is 8 with a remainder of 36.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 2464 from 2500 and we're left with 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 308

Advancing to step 5:
308 goes into 369 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 308 from 369 leaves us with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 308

Step 6:
The number 308 fits into 610 1 times, leaving a remainder of 302.
Record the quotient 1 as the next digit in the result. 
Result so far: 811.0
If we take 308 away from 610, we end up with 302.
Bring next digit (0) of the dividend behind the 302 and repeat the process: 3020 / 308

Going ahead to step 7:
When dividing 3020 by 308, we get 9 with a remainder of 248.
Write down 9 as next digit of the result. 
Result so far: 8119.0
Subtracting 2772 from 3020 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 8:
2480 divided by 308 is 8 with a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 8119.8
Subtracting 2464 from 2480 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 308, we get 0 with a remainder of 160.
The next digit of our result is 0. 
Result so far: 8119.8
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 10:
If we divide 1600 by 308, we get 5 and a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 8119.805
Deduct 1540 from 1600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
308 goes into 600 1 times with a remainder of 292.
Use 1 as the next digit of our solution. 
Result so far: 8119.8051
If we subtract 308 from 600, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 12:
2920 divided by 308 is 9 with a remainder of 148.
Put 9 as the next digit of the answer. 
Result so far: 8119.80519
Subtracting 2772 from 2920 leaves us with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 13:
The number 308 fits into 1480 4 times, leaving a remainder of 248.
Put 4 as the next digit of the answer. 
Result so far: 8119.805194
Subtract 1232 from 1480 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 14:
308 can be fit into 2480 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 8119.8051948
Subtract 2464 from 2480 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
If we divide 160 by 308, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 8119.8051948
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

In conclusion, the division gives 8119.8051948 with a balance of 1.6e-07.
