We're dividing 71545189 by 305 
The aim is to understand the frequency of 305 in 71545189.

Let's proceed to step 1:
305 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 305

Step 2:
305 goes into 71 0 times with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 305

On to step 3:
The number 305 fits into 715 2 times, leaving a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 610 from 715 and we're left with 105.
Fetch the next digit (4) from the dividend, attach it to 105 and continue: 1054 / 305

On to step 4:
305 can be fit into 1054 3 times, resulting in a remainder of 139.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 915 from 1054 and we're left with 139.
Fetch the next digit (5) from the dividend, attach it to 139 and continue: 1395 / 305

On to step 5:
If we divide 1395 by 305, we get 4 and a remainder of 175.
Record the quotient 4 as the next digit in the result. 
Result so far: 234.0
If we subtract 1220 from 1395, we get 175.
Include the next digit (1) from the dividend after 175, then repeat: 1751 / 305

Advancing to step 6:
305 goes into 1751 5 times with a remainder of 226.
Record the quotient 5 as the next digit in the result. 
Result so far: 2345.0
If we take 1525 away from 1751, we end up with 226.
Include the next digit (8) from the dividend after 226, then repeat: 2268 / 305

Let's proceed to step 7:
When dividing 2268 by 305, we get 7 with a remainder of 133.
Write down 7 as next digit of the result. 
Result so far: 23457.0
If we subtract 2135 from 2268, we get 133.
Take the next digit (9) from the dividend and append it to 133, then repeat: 1339 / 305

Going ahead to step 8:
The number 305 fits into 1339 4 times, leaving a remainder of 119.
The next digit of our result is 4. 
Result so far: 234574.0
Subtracting 1220 from 1339 leaves us with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 9:
The number 305 fits into 1190 3 times, leaving a remainder of 275.
Use 3 as the next digit of our solution. 
Result so far: 234574.3
If we subtract 915 from 1190, we get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Step 10:
If we divide 2750 by 305, we get 9 and a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 234574.39
Deduct 2745 from 2750 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 11:
305 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 234574.39
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 12:
500 divided by 305 is 1 with a remainder of 195.
Record the quotient 1 as the next digit in the result. 
Result so far: 234574.3901
If we subtract 305 from 500, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Let's proceed to step 13:
If we divide 1950 by 305, we get 6 and a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 234574.39016
The remainder is 120 after subtracting 1830 from 1950.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 14:
305 can be fit into 1200 3 times, resulting in a remainder of 285.
Write down 3 as next digit of the result. 
Result so far: 234574.390163
Subtracting 915 from 1200 leaves us with 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 15:
If we divide 2850 by 305, we get 9 and a remainder of 105.
The next digit of our result is 9. 
Result so far: 234574.3901639
Subtract 2745 from 2850 to get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 16:
305 goes into 1050 3 times with a remainder of 135.
Put 3 as the next digit of the answer. 
Result so far: 234574.39016393
If we subtract 915 from 1050, we get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 234574.39016393 and a remainder of 1.35e-07.
