We look at the division of 845377 by 71 
The aim is to understand the frequency of 71 in 845377.

Step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 71

Moving on to step 2:
84 divided by 71 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 71 from 84 leaves us with 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 71

Advancing to step 3:
If we divide 135 by 71, we get 1 and a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Deduct 71 from 135 and we're left with 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 71

Moving on to step 4:
When dividing 643 by 71, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 119.0
Subtracting 639 from 643 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 71

On to step 5:
71 can be fit into 47 0 times, resulting in a remainder of 47.
Write down 0 as next digit of the result. 
Result so far: 1190.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (7) from the dividend, attach it to 47 and continue: 477 / 71

Step 6:
477 divided by 71 is 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 11906.0
Subtracting 426 from 477 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
71 can be fit into 510 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 11906.7
If we subtract 497 from 510, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
71 goes into 130 1 times with a remainder of 59.
Put 1 as the next digit of the answer. 
Result so far: 11906.71
If we subtract 71 from 130, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 9:
590 divided by 71 is 8 with a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 11906.718
Subtract 568 from 590 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 10:
220 divided by 71 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 11906.7183
Subtracting 213 from 220 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 11:
The number 71 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 11906.7183
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
When dividing 700 by 71, we get 9 with a remainder of 61.
The next digit of our result is 9. 
Result so far: 11906.718309
If we take 639 away from 700, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 13:
71 can be fit into 610 8 times, resulting in a remainder of 42.
Put 8 as the next digit of the answer. 
Result so far: 11906.7183098
If we subtract 568 from 610, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
The number 71 fits into 420 5 times, leaving a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 11906.71830985
Subtracting 355 from 420 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Our division results in 11906.71830985 with a remaining 6.5e-08.
