We divide 901040 by 71
The aim is to understand the frequency of 71 in 901040.

Going ahead to step 1:
The number 71 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 71

On to step 2:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 71 from 90, we get 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 71

On to step 3:
71 can be fit into 191 2 times, resulting in 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:
490 divided by 71 is 6 with a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Subtracting 426 from 490 leaves us with 64.
Take the next digit (4) from the dividend and append it to 64, then repeat: 644 / 71

On to step 5:
When dividing 644 by 71, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 1269.0
Subtracting 639 from 644 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 71

Step 6:
50 divided by 71 is 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 12690.0
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 7:
If we divide 500 by 71, we get 7 and a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 12690.7
If we take 497 away from 500, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 71 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 12690.7
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 9:
When dividing 300 by 71, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 12690.704
Deduct 284 from 300 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
The number 71 fits into 160 2 times, leaving a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 12690.7042
If we subtract 142 from 160, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
180 divided by 71 is 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12690.70422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 12690.70422 with a remainder of 3.8e-05.
