We look at the division of 912404 by 71 
The aim is to understand the frequency of 71 in 912404.

Let's proceed to step 1:
71 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 71

Let's proceed to step 2:
If we divide 91 by 71, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 71 from 91 and we're left with 20.
Fetch the next digit (2) from the dividend, attach it to 20 and continue: 202 / 71

Moving on to step 3:
71 can be fit into 202 2 times, resulting in a remainder of 60.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 142 from 202, we get 60.
Bring next digit (4) of the dividend behind the 60 and repeat the process: 604 / 71

Let's proceed to step 4:
If we divide 604 by 71, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 128.0
Subtracting 568 from 604 leaves us with 36.
Append the next digit (0) from the dividend to 36 and continue with: 360 / 71

Let's proceed to step 5:
71 can be fit into 360 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 1285.0
Subtracting 355 from 360 leaves us with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 71

On to step 6:
When dividing 54 by 71, we get 0 with a remainder of 54.
Put 0 as the next digit of the answer. 
Result so far: 12850.0
Subtract 0 from 54 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
The number 71 fits into 540 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 12850.7
Subtract 497 from 540 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 8:
430 divided by 71 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12850.76
If we subtract 426 from 430, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
40 divided by 71 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12850.76
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
400 divided by 71 is 5 with a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 12850.7605
Subtracting 355 from 400 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 11:
The number 71 fits into 450 6 times, leaving a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12850.76056
Subtract 426 from 450 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
240 divided by 71 is 3 with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 12850.760563
If we take 213 away from 240, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 13:
270 divided by 71 is 3 with a remainder of 57.
The next digit of our result is 3. 
Result so far: 12850.7605633
If we subtract 213 from 270, we get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

After the division, we end up with 12850.7605633 and a remainder of 5.7e-07.
