We're dividing 430423 by 71 
The aim is to understand the frequency of 71 in 430423.

Advancing to step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 71

Step 2:
71 goes into 43 0 times with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 71

Advancing to step 3:
The number 71 fits into 430 6 times, leaving a remainder of 4.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 426 from 430 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 71

Going ahead to step 4:
The number 71 fits into 44 0 times, leaving a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 60.0
Subtracting 0 from 44 leaves us with 44.
Take the next digit (2) from the dividend and append it to 44, then repeat: 442 / 71

Let's proceed to step 5:
If we divide 442 by 71, we get 6 and a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 606.0
Subtracting 426 from 442 leaves us with 16.
Fetch the next digit (3) from the dividend, attach it to 16 and continue: 163 / 71

On to step 6:
The number 71 fits into 163 2 times, leaving a remainder of 21.
Use 2 as the next digit of our solution. 
Result so far: 6062.0
Subtracting 142 from 163 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
71 goes into 210 2 times with a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 6062.2
Subtract 142 from 210 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 8:
The number 71 fits into 680 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 6062.29
Subtract 639 from 680 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 9:
71 can be fit into 410 5 times, resulting in a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 6062.295
Subtract 355 from 410 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
71 goes into 550 7 times with a remainder of 53.
Use 7 as the next digit of our solution. 
Result so far: 6062.2957
Subtract 497 from 550 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
71 goes into 530 7 times with a remainder of 33.
Write down 7 as next digit of the result. 
Result so far: 6062.29577
Deduct 497 from 530 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The final outcome is 6062.29577, with a leftover of 3.3e-05.
