We're dividing 85184374 by 305 
The aim is to understand the frequency of 305 in 85184374.

Advancing to step 1:
8 divided by 305 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 305

Moving on to step 2:
85 divided by 305 is 0 with a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Fetch the next digit (1) from the dividend, attach it to 85 and continue: 851 / 305

Advancing to step 3:
When dividing 851 by 305, we get 2 with a remainder of 241.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 610 away from 851, we end up with 241.
Take the next digit (8) from the dividend and append it to 241, then repeat: 2418 / 305

Moving on to step 4:
When dividing 2418 by 305, we get 7 with a remainder of 283.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 2135 from 2418 to get 283.
Append the next digit (4) from the dividend to 283 and continue with: 2834 / 305

Let's proceed to step 5:
The number 305 fits into 2834 9 times, leaving a remainder of 89.
The next digit of our result is 9. 
Result so far: 279.0
If we subtract 2745 from 2834, we get 89.
Fetch the next digit (3) from the dividend, attach it to 89 and continue: 893 / 305

Step 6:
If we divide 893 by 305, we get 2 and a remainder of 283.
Put 2 as the next digit of the answer. 
Result so far: 2792.0
Deduct 610 from 893 and we're left with 283.
Bring next digit (7) of the dividend behind the 283 and repeat the process: 2837 / 305

Advancing to step 7:
When dividing 2837 by 305, we get 9 with a remainder of 92.
Put 9 as the next digit of the answer. 
Result so far: 27929.0
Deduct 2745 from 2837 and we're left with 92.
Append the next digit (4) from the dividend to 92 and continue with: 924 / 305

Advancing to step 8:
305 goes into 924 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 279293.0
Deduct 915 from 924 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 9:
When dividing 90 by 305, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 279293.0
If we subtract 0 from 90, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 10:
900 divided by 305 is 2 with a remainder of 290.
Record the quotient 2 as the next digit in the result. 
Result so far: 279293.02
If we take 610 away from 900, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

On to step 11:
305 can be fit into 2900 9 times, resulting in a remainder of 155.
Record the quotient 9 as the next digit in the result. 
Result so far: 279293.029
Subtracting 2745 from 2900 leaves us with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 12:
If we divide 1550 by 305, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 279293.0295
The remainder is 25 after subtracting 1525 from 1550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 13:
If we divide 250 by 305, we get 0 and a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 279293.0295
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Step 14:
305 goes into 2500 8 times with a remainder of 60.
Put 8 as the next digit of the answer. 
Result so far: 279293.029508
Deduct 2440 from 2500 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 15:
The number 305 fits into 600 1 times, leaving a remainder of 295.
The number 1 becomes the next digit in our result. 
Result so far: 279293.0295081
Subtracting 305 from 600 leaves us with 295.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

Let's proceed to step 16:
305 can be fit into 2950 9 times, resulting in a remainder of 205.
Write down 9 as next digit of the result. 
Result so far: 279293.02950819
If we subtract 2745 from 2950, we get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 279293.02950819 and a remainder of 2.05e-07.
