We divide 437852 by 71
The aim is to understand the frequency of 71 in 437852.

Going ahead to step 1:
When dividing 4 by 71, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 71

Step 2:
43 divided by 71 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 71

Advancing to step 3:
The number 71 fits into 437 6 times, leaving a remainder of 11.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 426 from 437 and we're left with 11.
Bring next digit (8) of the dividend behind the 11 and repeat the process: 118 / 71

Advancing to step 4:
71 goes into 118 1 times with a remainder of 47.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtracting 71 from 118 leaves us with 47.
Append the next digit (5) from the dividend to 47 and continue with: 475 / 71

Let's proceed to step 5:
The number 71 fits into 475 6 times, leaving a remainder of 49.
The number 6 becomes the next digit in our result. 
Result so far: 616.0
If we take 426 away from 475, we end up with 49.
Append the next digit (2) from the dividend to 49 and continue with: 492 / 71

On to step 6:
If we divide 492 by 71, we get 6 and a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 6166.0
Subtracting 426 from 492 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 7:
The number 71 fits into 660 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 6166.9
Subtracting 639 from 660 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.

Going ahead to step 8:
71 goes into 210 2 times with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 6166.92
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 9:
When dividing 680 by 71, we get 9 with a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 6166.929
Subtracting 639 from 680 leaves us 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.

On to step 10:
The number 71 fits into 410 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 6166.9295
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 11:
If we divide 550 by 71, we get 7 and a remainder of 53.
The number 7 becomes the next digit in our result. 
Result so far: 6166.92957
If we take 497 away from 550, we end up with 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 12:
71 can be fit into 530 7 times, resulting in a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 6166.929577
If we take 497 away from 530, we end up 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.

In conclusion, the division gives 6166.929577 with a balance of 3.3e-06.
