We look at the division of 52853004 by 308 
The aim is to understand the frequency of 308 in 52853004.

Going ahead to step 1:
If we divide 5 by 308, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 308

Advancing to step 2:
52 divided by 308 is 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (8) from the dividend, attach it to 52 and continue: 528 / 308

Let's proceed to step 3:
528 divided by 308 is 1 with a remainder of 220.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 308 from 528 to get 220.
Fetch the next digit (5) from the dividend, attach it to 220 and continue: 2205 / 308

Advancing to step 4:
2205 divided by 308 is 7 with a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
If we take 2156 away from 2205, we end up with 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 308

Let's proceed to step 5:
If we divide 493 by 308, we get 1 and a remainder of 185.
The next digit of our result is 1. 
Result so far: 171.0
Deduct 308 from 493 and we're left with 185.
Grab the next digit (0) from the dividend, add it to 185, then carry on: 1850 / 308

Let's proceed to step 6:
When dividing 1850 by 308, we get 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1716.0
Subtracting 1848 from 1850 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 308

Advancing to step 7:
20 divided by 308 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 17160.0
Subtract 0 from 20 to get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 308

Advancing to step 8:
When dividing 204 by 308, we get 0 with a remainder of 204.
Write down 0 as next digit of the result. 
Result so far: 171600.0
Subtract 0 from 204 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.

Going ahead to step 9:
When dividing 2040 by 308, we get 6 with a remainder of 192.
The next digit of our result is 6. 
Result so far: 171600.6
The remainder is 192 after subtracting 1848 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 10:
The number 308 fits into 1920 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 171600.66
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.

In conclusion, the division gives 171600.66 with a balance of 0.072.
