637228 divided by 71 
The aim is to understand the frequency of 71 in 637228.

Advancing to step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 71

Going ahead to step 2:
The number 71 fits into 63 0 times, leaving a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Include the next digit (7) from the dividend after 63, then repeat: 637 / 71

Going ahead to step 3:
71 can be fit into 637 8 times, resulting in a remainder of 69.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 69 after subtracting 568 from 637.
Include the next digit (2) from the dividend after 69, then repeat: 692 / 71

Let's proceed to step 4:
692 divided by 71 is 9 with a remainder of 53.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
If we take 639 away from 692, we end up with 53.
Take the next digit (2) from the dividend and append it to 53, then repeat: 532 / 71

Step 5:
When dividing 532 by 71, we get 7 with a remainder of 35.
Put 7 as the next digit of the answer. 
Result so far: 897.0
Subtracting 497 from 532 leaves us with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 71

Going ahead to step 6:
When dividing 358 by 71, we get 5 with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 8975.0
Subtract 355 from 358 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
71 can be fit into 30 0 times, resulting in a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 8975.0
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.

Advancing to step 8:
When dividing 300 by 71, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 8975.04
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.

Advancing to step 9:
71 can be fit into 160 2 times, resulting in a remainder of 18.
The next digit of our result is 2. 
Result so far: 8975.042
Subtract 142 from 160 to 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.

On to step 10:
When dividing 180 by 71, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 8975.0422
If we take 142 away from 180, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 8975.0422 and a remainder of 0.00038.
