We're dividing 35230370 by 71 
The aim is to understand the frequency of 71 in 35230370.

On to step 1:
3 divided by 71 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 71

Going ahead to step 2:
When dividing 35 by 71, we get 0 with a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 35 after subtracting 0 from 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 71

Step 3:
When dividing 352 by 71, we get 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 284 from 352 and we're left with 68.
Include the next digit (3) from the dividend after 68, then repeat: 683 / 71

Moving on to step 4:
When dividing 683 by 71, we get 9 with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
Subtract 639 from 683 to get 44.
Bring next digit (0) of the dividend behind the 44 and repeat the process: 440 / 71

On to step 5:
When dividing 440 by 71, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 496.0
The remainder is 14 after subtracting 426 from 440.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 71

Going ahead to step 6:
71 can be fit into 143 2 times, resulting in a remainder of 1.
The next digit of our result is 2. 
Result so far: 4962.0
If we take 142 away from 143, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 71

On to step 7:
When dividing 17 by 71, we get 0 with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 49620.0
If we subtract 0 from 17, we get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 71

On to step 8:
When dividing 170 by 71, we get 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 496202.0
Deduct 142 from 170 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
280 divided by 71 is 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 496202.3
The remainder is 67 after subtracting 213 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 10:
71 goes into 670 9 times with a remainder of 31.
The next digit of our result is 9. 
Result so far: 496202.39
Subtracting 639 from 670 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 11:
The number 71 fits into 310 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 496202.394
Subtract 284 from 310 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 12:
71 can be fit into 260 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 496202.3943
The remainder is 47 after subtracting 213 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 13:
71 can be fit into 470 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 496202.39436
The remainder is 44 after subtracting 426 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 14:
71 can be fit into 440 6 times, resulting in a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 496202.394366
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 496202.394366 with a remainder of 1.4e-06.
