901009 divided by 71 
The aim is to understand the frequency of 71 in 901009.

Moving on to step 1:
If we divide 9 by 71, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 71

Advancing to step 2:
90 divided by 71 is 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 71 from 90 and we're left with 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 71

Moving on to step 3:
71 goes into 191 2 times with a remainder of 49.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 142 from 191 leaves us with 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 71

Moving on to step 4:
71 goes into 490 6 times with a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 126.0
If we take 426 away from 490, we end up with 64.
Include the next digit (0) from the dividend after 64, then repeat: 640 / 71

Let's proceed to step 5:
The number 71 fits into 640 9 times, leaving a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1269.0
Subtracting 639 from 640 leaves us with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 71

Advancing to step 6:
71 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 12690.0
If we subtract 0 from 19, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
When dividing 190 by 71, we get 2 with a remainder of 48.
The next digit of our result is 2. 
Result so far: 12690.2
Deduct 142 from 190 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 8:
The number 71 fits into 480 6 times, leaving a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 12690.26
If we subtract 426 from 480, we 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.

Going ahead to step 9:
71 can be fit into 540 7 times, resulting in a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 12690.267
If we subtract 497 from 540, we 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.

Going ahead to step 10:
When dividing 430 by 71, we get 6 with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 12690.2676
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.

Let's proceed to step 11:
The number 71 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 12690.2676
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 71, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 12690.267605
The remainder is 45 after subtracting 355 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 13:
71 goes into 450 6 times with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 12690.2676056
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.

Moving on to step 14:
When dividing 240 by 71, we get 3 with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 12690.26760563
If we subtract 213 from 240, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 12690.26760563 with a balance of 2.7e-08.
