We're dividing 672951 by 71 
The aim is to understand the frequency of 71 in 672951.

Step 1:
When dividing 6 by 71, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 71

On to step 2:
If we divide 67 by 71, we get 0 and a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Include the next digit (2) from the dividend after 67, then repeat: 672 / 71

Going ahead to step 3:
71 goes into 672 9 times with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 33 after subtracting 639 from 672.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 71

Let's proceed to step 4:
339 divided by 71 is 4 with a remainder of 55.
Write down 4 as next digit of the result. 
Result so far: 94.0
The remainder is 55 after subtracting 284 from 339.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 71

Advancing to step 5:
555 divided by 71 is 7 with a remainder of 58.
The next digit of our result is 7. 
Result so far: 947.0
Deduct 497 from 555 and we're left with 58.
Fetch the next digit (1) from the dividend, attach it to 58 and continue: 581 / 71

Going ahead to step 6:
The number 71 fits into 581 8 times, leaving a remainder of 13.
Use 8 as the next digit of our solution. 
Result so far: 9478.0
Subtract 568 from 581 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
When dividing 130 by 71, we get 1 with a remainder of 59.
Use 1 as the next digit of our solution. 
Result so far: 9478.1
The remainder is 59 after subtracting 71 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
If we divide 590 by 71, we get 8 and a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 9478.18
Subtract 568 from 590 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
71 can be fit into 220 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 9478.183
Subtracting 213 from 220 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 71 is 0 with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 9478.183
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 11:
When dividing 700 by 71, we get 9 with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 9478.18309
If we subtract 639 from 700, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
610 divided by 71 is 8 with a remainder of 42.
Write down 8 as next digit of the result. 
Result so far: 9478.183098
If we take 568 away from 610, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 13:
When dividing 420 by 71, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 9478.1830985
Subtracting 355 from 420 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 14:
When dividing 650 by 71, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 9478.18309859
The remainder is 11 after subtracting 639 from 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 9478.18309859 with a remainder of 1.1e-08.
