We're dividing 2123699 by 308 
The aim is to understand the frequency of 308 in 2123699.

Moving on to step 1:
The number 308 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 308

Advancing to step 2:
308 goes into 21 0 times with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 308

Moving on to step 3:
The number 308 fits into 212 0 times, leaving a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 212 after subtracting 0 from 212.
Append the next digit (3) from the dividend to 212 and continue with: 2123 / 308

On to step 4:
The number 308 fits into 2123 6 times, leaving a remainder of 275.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 1848 from 2123 and we're left with 275.
Append the next digit (6) from the dividend to 275 and continue with: 2756 / 308

Advancing to step 5:
308 can be fit into 2756 8 times, resulting in a remainder of 292.
The next digit of our result is 8. 
Result so far: 68.0
The remainder is 292 after subtracting 2464 from 2756.
Take the next digit (9) from the dividend and append it to 292, then repeat: 2929 / 308

Moving on to step 6:
If we divide 2929 by 308, we get 9 and a remainder of 157.
The number 9 becomes the next digit in our result. 
Result so far: 689.0
Subtracting 2772 from 2929 leaves us with 157.
Grab the next digit (9) from the dividend, add it to 157, then carry on: 1579 / 308

Advancing to step 7:
308 goes into 1579 5 times with a remainder of 39.
Put 5 as the next digit of the answer. 
Result so far: 6895.0
Deduct 1540 from 1579 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
When dividing 390 by 308, we get 1 with a remainder of 82.
Record the quotient 1 as the next digit in the result. 
Result so far: 6895.1
Subtract 308 from 390 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
820 divided by 308 is 2 with a remainder of 204.
Record the quotient 2 as the next digit in the result. 
Result so far: 6895.12
Subtract 616 from 820 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
If we divide 2040 by 308, we get 6 and a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 6895.126
Deduct 1848 from 2040 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

On to step 11:
1920 divided by 308 is 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 6895.1266
The remainder is 72 after subtracting 1848 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The quotient of the division is 6895.1266, and the remainder is 0.00072.
