We're dividing 906440 by 71 
The aim is to understand the frequency of 71 in 906440.

Let's proceed to step 1:
71 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 71

On to step 2:
If we divide 90 by 71, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 71 from 90 to get 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 71

Advancing to step 3:
The number 71 fits into 196 2 times, leaving a remainder of 54.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 142 away from 196, we end up with 54.
Bring next digit (4) of the dividend behind the 54 and repeat the process: 544 / 71

Advancing to step 4:
71 can be fit into 544 7 times, resulting in a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 127.0
If we take 497 away from 544, we end up with 47.
Append the next digit (4) from the dividend to 47 and continue with: 474 / 71

Advancing to step 5:
474 divided by 71 is 6 with a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 1276.0
Subtract 426 from 474 to get 48.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 71

Going ahead to step 6:
When dividing 480 by 71, we get 6 with a remainder of 54.
The next digit of our result is 6. 
Result so far: 12766.0
The remainder is 54 after subtracting 426 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 7:
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: 12766.7
The remainder is 43 after subtracting 497 from 540.
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:
71 can be fit into 430 6 times, resulting in a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 12766.76
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.

Moving on to step 9:
The number 71 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12766.76
If we subtract 0 from 40, we 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.

Moving on to step 10:
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: 12766.7605
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 11:
If we divide 450 by 71, we get 6 and a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 12766.76056
The remainder is 24 after subtracting 426 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
71 can be fit into 240 3 times, resulting in a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 12766.760563
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.

Step 13:
If we divide 270 by 71, we get 3 and a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 12766.7605633
The remainder is 57 after subtracting 213 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Our division results in 12766.7605633 with a remaining 5.7e-07.
