We look at the division of 39629395 by 71 
The aim is to understand the frequency of 71 in 39629395.

Going ahead to step 1:
If we divide 3 by 71, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 71

Step 2:
39 divided by 71 is 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 71

Advancing to step 3:
71 goes into 396 5 times with a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 355 from 396 leaves us with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 71

Going ahead to step 4:
The number 71 fits into 412 5 times, leaving a remainder of 57.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
If we take 355 away from 412, we end up with 57.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 71

Going ahead to step 5:
71 can be fit into 579 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 558.0
If we take 568 away from 579, we end up with 11.
Grab the next digit (3) from the dividend, add it to 11, then carry on: 113 / 71

Step 6:
If we divide 113 by 71, we get 1 and a remainder of 42.
Write down 1 as next digit of the result. 
Result so far: 5581.0
The remainder is 42 after subtracting 71 from 113.
Grab the next digit (9) from the dividend, add it to 42, then carry on: 429 / 71

Going ahead to step 7:
71 can be fit into 429 6 times, resulting in a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 55816.0
If we take 426 away from 429, we end up with 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 71

Moving on to step 8:
35 divided by 71 is 0 with a remainder of 35.
Use 0 as the next digit of our solution. 
Result so far: 558160.0
Deduct 0 from 35 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 71 fits into 350 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 558160.4
Subtract 284 from 350 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
If we divide 660 by 71, we get 9 and a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 558160.49
If we subtract 639 from 660, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 11:
If we divide 210 by 71, we get 2 and a remainder of 68.
Use 2 as the next digit of our solution. 
Result so far: 558160.492
If we take 142 away from 210, we end up with 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 12:
71 goes into 680 9 times with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 558160.4929
Deduct 639 from 680 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 13:
410 divided by 71 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 558160.49295
Subtracting 355 from 410 leaves us with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 14:
550 divided by 71 is 7 with a remainder of 53.
Put 7 as the next digit of the answer. 
Result so far: 558160.492957
If we subtract 497 from 550, we 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.

Let's proceed to step 15:
If we divide 530 by 71, we get 7 and a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 558160.4929577
Subtract 497 from 530 to get 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 result is 558160.4929577 with a remainder of 3.3e-07.
