We look at the division of 852073 by 71 
The aim is to understand the frequency of 71 in 852073.

Step 1:
If we divide 8 by 71, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 71

On to step 2:
When dividing 85 by 71, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 71 from 85 leaves us with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 71

Let's proceed to step 3:
71 goes into 142 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 142 from 142, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 71

On to step 4:
71 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 120.0
If we subtract 0 from 0, we get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 71

Let's proceed to step 5:
71 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 1200.0
If we take 0 away from 7, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 71

Step 6:
71 can be fit into 73 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 12001.0
Deduct 71 from 73 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
71 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 12001.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
When dividing 200 by 71, we get 2 with a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 12001.02
The remainder is 58 after subtracting 142 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
71 can be fit into 580 8 times, resulting in a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 12001.028
Subtract 568 from 580 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 10:
When dividing 120 by 71, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 12001.0281
Subtracting 71 from 120 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 11:
When dividing 490 by 71, we get 6 with a remainder of 64.
Write down 6 as next digit of the result. 
Result so far: 12001.02816
Subtracting 426 from 490 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 12:
If we divide 640 by 71, we get 9 and a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 12001.028169
Subtract 639 from 640 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 13:
When dividing 10 by 71, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 12001.028169
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 14:
If we divide 100 by 71, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 12001.02816901
Deduct 71 from 100 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

In conclusion, the division gives 12001.02816901 with a balance of 2.9e-08.
